ID-1: A Demonstration of the NorNet Core Research Testbed for Multi-Homed Systems

Presentation: 2-2:20pm

Abstract: Due to the availability of reasonably inexpensive Internet connections, cloud computing is becoming increasingly more popular and widespread. Instead of maintaining servers locally, services are provided by remote virtual servers at data centers. In the recent years, a lot of research work has been done in the area of server redundancy and service migration. However, for many cloud computing users today, the access to the Internet constitutes a single point of failure. That is, if such an Internet connection is broken, all cloud services become un- available. Further research on network resilience is necessary. The Simula Research Laboratory has therefore established the NORNET project, in order to create an open, multi-site research testbed platform for network resilience and multi-path transport experiments in real Internet setups. Particularly, all NORNET sites are multi-homed, i.e. connected to at least two Internet Service Providers (ISP). NORNET CORE denotes the wired part of the NORNET testbed. The testbed consists of research nodes distributed all over the country of Norway as well as further nodes in Sweden, Germany and China.
In order to illustratively demonstrate the functionalities of NORNET CORE in a multi-site, multi-homed Internet setup, a demonstration platform has been designed and implemented as part of a Masters thesis. The demonstration setup is particularly intended to also show the basic functionalities of NORNET CORE to an audience without a broader knowledge of resilience and multi-path transport. It particularly allows to demonstrate the implications of ISP combinations on QoS performance (bandwidth, delay, etc.), with support for IPv4 and IPv6 as well as state-of-the-art transport protocols like the Stream Control Transmission Protocol (SCTP) as well as Multi-Path TCP (MPTCP).

Abstract: OpenFlow is not a simple architecture and protocol, with five versions and more than a thousand pages of specification it can be daunting to all but the protocol lawyers. Newcomers to OpenFlow must read protocol specification documents and tediously setup lab environments to gain an understanding. Setting up an OpenFlow environment, even through emulation tools like Mininet, still involves a bit of effort, and doesn't really explain how OpenFlow works or illustrates the internals of the OpenFlow data plane. In this demo, we present Flowsim, a new OpenFlow switch simulator that requires no setup, and allows developers to experiment with various data plane capabilities provided by each version of OpenFlow (1.0, 1.1, 1.2, 1.3, 1.4).
Flowsim is a web application that enables the users to configure their own OpenFlow switches, issue OpenFlow messages, inject custom packet sequences into the data plane, and observe the resulting behavior. During a simulation the life cycle of an injected packet is visualized as it traverses the OpenFlow data plane. The user is presented with visualizations that included packet arrival, key extraction, table selection, flow selection, and action application.
Switch profiles are configured by specifying the actions, matches, and instructions capabilities that are supported by their switch. Users have the ability to configure a custom OpenFlow switch profile or choose a profile based on a vendor switch such as a Pica8. Once a switch is configured users issue OpenFlow messages such as Flowmod to populate the Flowtables of the switch. Users have the ability to craft packets and inject them into the data plane during the simulation. As a user crafted packet traverses the data plane, visualizations of the packets progress through data plane are presented to the user. The simulation results in a detailed summary of table selection flow selection, and action application.

ID-3: NFV Management and Orchestration for Flexible Service Chaining
Track: Networking and Information
Presentation: 2:40 - 3:00pm
Authors: Koji Tsubouchi and Shinya Kano; Fujitsu Laboratories LTD, Japan
Abstract: NFV (Network Functions Virtualization) and service chaining are recognized as key technologies in the network industries. An issue on the current service chaining is that it is rather static and inflexible. Also, it is a challenge to support various network functions to compose service chains because some of them translate addresses of packets and it is difficult to construct proper path. This paper demonstrates flexible service chaining using NFV management and orchestration to cover these issues.

Abstract: Network Function Virtualization (NFV) has emerged as an operator proposal for offering network services with network functions implemented in software, which may be located in Data Centers (DCs), network nodes or even in a virtual machine. Following the NFV concept, any network function can be virtualized and located in anyplace in order simplify the management of heterogeneous hardware platforms. This demonstration pretends to show the extraction of a network function and the management of it without affecting the network service between two DC. In addition, the duplication or migration of the network function is shown, moving it through the network. In order to expose the proposed ideas we based on the virtualization of the routing function over a Software Defined Networks (SDN) domain.

Abstract: IEEE NGSON (Next Generation Service Overlay Network) is a framework of Internet Protocol (IP)-based service overlay networks which offers context-aware, dynamically adaptive and self-organizing networking capabilities that are independent of underlying networks. NGSON enables network operators, service/content providers, and end users to provide and consume composite services. The scope of services in NGSON includes Physical Network Functions (PNF), Virtual Network Functions (VNF), User Hosted Functions (UHF), IT enablers and services from different verticals. All these services and functions are used to create an E2E Network Service and Business Service. This demo provides the relation of NGSON in NFV context and demonstrates the methods of virtualization of functions outside operators’ domain, creation of a context–aware composite network service by the operator including functions described above and ensure service continuity in the event of failure in such a composite service environment.

Abstract: Traffic and resource monitoring is the essential function for large-scale enterprises, service providers, and network operators to ensure reliability, availability, and security of their resources. For this reason, many large-scale enterprises and providers have been investing in various standalone dedicated monitoring solutions. However, they find the cost of a dedicated standalone appliance per-feature prohibitive, inflexible, slow to install and difficult to maintain. Network Function Virtualization (NFV)-based virtualization trends represent an attractive opportunity for such stakeholders trying to meet the above requirements while controlling OPEX and CAPEX. In this paper, we propose a novel architecture and proof-of-concept demonstration of a unified virtual monitoring and analysis function (UVMAF) built over multi-core whitebox server for SDN-based large-scale networks.

Abstract: Network operators are gearing up for next generation architectures where software centric models become dominant. This is in contrast to conventional and legacy systems heavily based on dedicated hardware and overly complex workflows and operations: a dramatic shift taking full advantage of emerging cloud computing technologies such as NFV (Network Functions Virtualization) and SDN (Software Defined Networking).
The telecommunications industry is not only seeking leaner and a more dynamic infrastructure and platforms that are better able to address ever pressing capacity needs, but also agile development, services and operations benefiting from unparalleled elasticity meeting demand curves and under remarkable double digit cost efficiencies. This is a game changing paradigm fostering: openness, programmability and automation through the service delivery lifecycle. Moreover, it involves new behaviors, workstyles and organization cultures raising productivity and competitiveness levels, which are superseding traditional roles and technical responsibilities.
This online demonstration is supported by CIC, Alcatel-Lucent’s Cloud Innovation Center, leveraging CloudBand’s Management System and Cloud Nodes jointly with Nuage Networks’ SDN framework. This discussion illustrates the automated onboarding of several VNF (Virtual Network Functions) via recipes and it does so in the context of a distributed carrier cloud environment that is multi-tenant, where applications share pools of underlying virtual resources and streamlined processes. The live demo proceeds to feature virtual network services that are dynamically composed, deployed, monitored and modified under an agile service chaining scenario, all steps visualized in real time.
The conversation at this demo station also addresses NFV maturity levels, technology readiness, known challenges, deployment strategies, and equally relevant, new business models and fundamentals, behavioral economics and a business case sample prepared in partnership with a network operator. This demonstration is “camera ready” at the time of submitting this proposal.

ID-11: Title: Highly Flexible and Scalable 5G Platform for Gbps Validation
Track: Access Technologies
Presentation: 2-2:20pm

Abstract:
The exceptional growth in areas of mobile subscriber, wireless network access, mobile services and applications shows evidences of the continuous expansion of cellular communication . The 5G (fifth generation) mobile communication standard, the formulation of which is still in incubation, aims to solve future challenges ranging from the avalanche of traffic volume, massive growth in connected devices to very diverse use cases and requirements.
However, as the standard formulation evolves, it is crucial to have a flexible and scalable validation platform capable of handling any specification variation. This poster paper/demonstration presents an integrated 5G radio access experiment platform with extraordinary flexibility and scalability for newly defined features, and able to deliver higher data rates without changing hardware architecture. To be specific, this platform is developed to achieve a data rate higher than 1Gbps data rate by using 24 antennas and analog carrier aggregation technology.
A multi-RAT (Radio Access Technology) platform architecture, comprising of RRH (Remote Radio Head) and BBU (Baseband Unit) sub-systems, can be easily implemented by software configuration to facilitate applicability. A super-heterodyne architecture is designed for RRH’s front-end circuit to support tunable intermediate frequency (IF) ranges from 70MHz to 6GHz. The BBU sub-system, comprising 5 multi-core DSP EVMs (TI TMS320TCI6614 EVM), supports the implementation of principal SDR functions. By re-molding the baseband software in DSP cores, this platform can be practiced as a 5G mobile communication system or as any other RAT system such as 4G or Wi-Fi. Besides, it supports fast prototyping and validation for new physical layer technologies or features emerged along with 5G standard’s evolution.
The communication between BBU and RRH is achieved by CPRI-based high speed interface. The IF part of the RRH is implemented by ADI AD9361 SDR System Development Kit, which is software definable and supports full IF functions, including ADC/DAC, BPF(Band Pass Filter) and gain control. Although only 56MHz bandwidth is supported for one single IF component, a wide band transmission can be realized via an innovative design of analog carrier aggregation of multiple 56MHz bands . The IF output signal is then up converted to the target RF frequency by the RF front-end circuit. By simply employing 1-to-N (N-to-1) splitter (combiner), the number of antennas can be adjusted easily and resiliently, and advanced multi-antenna techniques such as massive MIMO can therefore be facilitated.
The upper layer protocols are implemented in a dedicated server, which is connected with BBU through 10-Gigabit Ethernet. Such a design approach allows the system to enjoy the server’s rich computing capability, in order to undertake more flexible and more rapid deployment for evolved protocols. Moreover, the computing power of the server and can be further leveraged in the future to carry out multi-RAT virtualization.
With this highly flexible and scalable platform, it not only significantly reduces the installation and hardware cost, but also ensures fast deployment of new technologies in practical platform. Such virtue greatly accelerates the production cycle, and permits reliable initial lab, field trials, proof of concepts, and system verification from the very early stage.

Abstract: Next generation wireless networks (5G) have to cope with significant traffic increase due to heterogeneity of different applications such as high quality video and cloud based applications. Such requirements create the need for a revolutionary change in architecture rather than a series of local and incremental technology updates. A dense heterogeneous deployment of small cells such as pico/femto cells in addition to high power macro cells is foreseen as one of the potential solutions to achieve these requirements. Such a deployment requires innovation at all layers of communication protocol stack (PHY, MAC and higher layers). Moreover, all the new algorithms also need validation in a real-time testbed. However, the ever increasing complexity in all layers of current and future generations of cellular wireless systems has made an end-to-end demonstration of the network limited to industrial research labs or large academic institutions. SDR prototyping for showing such algorithms requires a need to overcome several challenges which arise due to the use of different design flows to address different components of the system (i.e. RF, baseband, and protocol stack). In addition, the components may lack a common abstraction layer. This can result in complications and delays during system development and integration. The NI LabVIEW graphical system design software is able to address these challenges by providing a common development environment for all the heterogeneous elements in the NI SDR system (i.e., the GPP, RTOS, FPGA, converters and RF components), with tight hardware/software integration and a good abstraction layer. This integrated design environment is the primary reason we chose NI LabVIEW SDR platform for prototyping and it enabled us to quickly reach an initial working version of our demonstration system and rapidly iterate on that design. In this demo, we show a LabVIEW based PXI platform in which LTE-like SISO OFDM PHY Layer is integrated with an open source NS-3 protocol stack to prototype PHY/MAC cross layer algorithms within EU FP7 CROWD project (http://www.ict-crowd.eu), which proposes Software Defined Networking (SDN) framework as a solution to tame dense deployment of wireless networks.

Abstract: Experimental vehicle-to-vehicle communication prototyping systems have been developed recently to operate at a 5.9 GHz band for which the channel characterization and the Power Delay Profile measurements are standardized by ITU. These systems operate over a 10 MHz band using OFDM receivers with channel estimators. The vehicle-to-vehicle communication standard is given by IEEE 802.11 p.
This prototype demonstration, developed by MKGSYS Ltd, will present an end-to-end transmission and channel emulation rapid prototyping platform using a National Instruments USRP RIO 2953R transceiver and LabVIEW software for IEEE 802.11 p wireless communication over vehicle-to-vehicle communication channels.
This rapid prototyping platform could be configured to operate as a 2×2 MIMO with FPGA based real-time channel emulation and real RF transmission paths. The RF front end baseband processing operates at 120MS/s rate. The channel emulator operates at 100MS/s and the transceivers operate at the sampling rate determined by the transmission symbol rate. At different stages of the prototype implementation the sampling rates are either up or down converted using interpolation (up sampling) and decimation (down sampling) methods.
The National Instruments (NI) USRP RIO 2953R uses a Xilinx Virtex-7 FPGA. NI LabVIEW has been used to implement several Xilinx FIR filters using FPGA single cycle loops for filtering, interpolation and decimation purposes. Single Cycle Loops have been synchronised to provide an end-to-end streaming operation. The parameters for the IEEE 802.11p are used for USRP RIO 2953R transceiver implementation at FPGA level. The USRP RIO 2953 hardware and FPGA programming are used to provide a baseband vehicle-to-vehicle channel emulator in accordance with the vehicle-to-vehicle channel Power Delay Profiles.
The demonstration system uses LabVIEW FPGA programs for channel estimation and vehicle-to-vehicle communication transceiver implementation for a 5G mobile radio prototype system based on the IEEE 802.11 p wireless communication standard.

Abstract: Programmable hardware devices, such as FPGAs, are used frequently as prototyping tools for the implementation of new products, algorithms, and other proofs of concept. However, in order to integrate these prototypes into the real-world environments where they will be used, careful consideration must be given to the features of the platform in order to achieve the necessary interoperability requirements. In addition, the value of a prototype increases dramatically when system level designers can use it directly and rapidly iterate through different architectures and implementations without the need for independent design expertise and time-intensive specification and validation hand-offs. This demo highlights a complete hardware platform and software solution for rapid system prototyping of a wide range of target applications, including 5G femtocells, 5G user equipment, and media or internet-of-things gateways.

Abstract: In order to increase spectral efficiency of current commercial cellular systems, researchers are continuing to explore new physical layer techniques such as massive MIMO, new waveforms, network densification, mmWave and many others. Prototyping is becoming an essential part of 5G research in order to prove the viability of these concepts and drive them into standardization, eventually. Nevertheless, mastering the complex hardware-software environment, required to prototype communications systems, poses a formidable challenge to small research teams. Most often, prototyping is driven by algorithm researchers whose core interest is to investigate an isolated portion of a communications system only, but who will still need vast infrastructure around this core component to conduct the actual experiment.
NI hardware-software platforms’ enable researchers to innovate faster by providing a path from theoretical research to rapid prototyping. The modular hardware concept, including standard PCs, real time controllers and FPGA modules with fast interconnects, allows to scale prototypes in terms of processing power, channel count and I/O bandwidth. This hardware is made available to the researcher in an abstracted, unified fashion using a single programming environment – LabVIEW.
To further enable researchers, National Instruments has been developing a real time PHY/MAC layer IP research platform, based on the 3GPP LTE standard. Conceptually, this research platform is designed such that all the essential components, for example, coding, synchronization, modulation, control channels, etc. are made available to the researcher. Modularity allows to replace these components by the proprietary component the researcher focuses on, for instance, modulator and demodulator for 5G waveform research. This concept is expected to reduce the ramp-up time of 5G prototyping projects by orders of magnitude.
As part of this demonstration, we will show an application running on the out-of-the-box base line research platform. In a second part, we will show an example of how researchers are able to integrate their individual 5G concepts into the research platform.

Abstract: Lund University and National Instruments will demonstrate a flexible test bed for massive MIMO, based on the NI PXI and USRP software defined radio platforms, combined with LabVIEW graphical system design software. Massive MIMO relies on coherent transmission and reception on large numbers of antenna elements, allowing efficient use of the propagation environment for spatial multiplex of many communication links. Massive MIMO is also considered one of the most promising technologies for substantial increase of spectral efficiency in future wireless systems. Theoretical studies show that, in favorable propagation conditions, both spectral and radiated energy efficiencies can be improved by one or more orders of magnitude. Initial measurements also show that real propagation environments can be favorable, in the sense that a large fraction of the theoretical gains can be harvested. The time has come to extend investigations from simulations and theory to real-life environments, with test beds capable of real-time massive MIMO transmissions in real communication scenarios. This what is being demonstrated by Lund University and National Instruments. The demonstrated test bed is a subset of the 100-antenna test bed system built at Lund University using National Instruments hardware and software. We will show the overall architecture of the test bed and how it is configured for different tests. Real-time communication between the massive MIMO base station and single-antenna terminals will be demonstrated, in what we believe to be the first public demonstration of its kind.

Abstract: The exponential growth in mobile traffic and the ubiquitous access requirement encourage the industry to look for new technology candidates for the next generation (5G) wireless communication networks, among which, physical layer breakthroughs in waveforms and multiple access technologies are no doubt cornerstones for any generation [1].
Sparse code multiple access (SCMA) [2], proposed as a key enabling new waveform and multiple access technology for 5G physical layer, has shown its capability of greatly increasing the number of simultaneously served connections (keeping the same spectrum efficiency required by each connection), the so-called system overloading gain, and better link quality compared with existing non-orthogonal multiple access schemes, the so called shaping gain and spreading diversity gain. On top of the direct gains, second order benefits such as low latency and low overhead multiple access have also been envisioned [3].
In general, SCMA can be seen as a multi-dimensional codebook-based non-orthogonal spreading technique. In SCMA, the procedures of bits to QAM symbol mapping and frequency domain spreading are combined together and optimized jointly thus incoming bits are directly mapped to multi-dimensional codewords of SCMA codebook sets [4]. Shaping gain of a multi-dimensional constellation is one of the main reasons for the link level performance improvement. Moreover, the sparsity of SCMA codewords facilitates SCMA to adopt low complexity reception techniques such as message passing algorithm (MPA), while keeping close to optimal maximum likelihood (ML) performance. Figure 1 shows an illustrative example of 6 users transmit in 4 resource units using SCMA, thus having 150% overloading gain.
In order to verify the SCMA technology and its advantages in real communication systems, we have developed a SCMA based uplink multi-user system prototype on real-time hardware platform. Our demo system consists of 1 base station with 2 antennas for diversity combined receiving and in total 14 UEs with 1 antenna each for uplink access and data transmission. The basic system configurations of our demo system are set to align with the current LTE TDD system. In particular, we use LTE TDD frame structure configuration1 and the LTE physical layer OFDMA is implemented as baseline for performance comparison. While keeping each user’s (or stream’s) spectrum efficiency requirement the same (so as to guarantee the same quality of service), the major difference for the two systems is
o LTE baseline: Multiple UEs use orthogonally separated resource blocks to transmit their data respectively as done in current LTE OFDMA based systems.
o Proposal SCMA: Multiple UEs use the same blocks of resources and apply the proposed SCMA technique to access and transmit data to base station simultaneously.
Our Demo can run in LTE mode and SCMA mode separately, and can be switched from one mode to another in real time. We would show that by applying the SCMA technology, 150% to 300% overloading in network connections and network throughput are available, compared with orthogonal multiple access baseline of 4G LTE. For instance, the 150% overloading gain can be interpreted as follows. Given the data volume demand for each user to be 12 RB, a system with total 48 RB can serve at most 4 users using orthogonal LTE OFDMA. However, with SCMA, codebook design supports 6 users with the same amount of data to share the 48 RBs simultaneously, thus actually 12*6 = 72 RB are actually delivered other than 12*4 = 48 RB, resulting in the gain of 72/48 = 150%. The 300% gain is supported in a similar way but with different codebook design, in which case, 12 users each with 2 streams can access and transmit simultaneous with SCMA, while for LTE OFDMA, only 4 users out of the 12 can transmit.
Moreover, we may further combine SCMA with other non-orthogonal waveforms to improve the spectrum shape and reduce out-of-band emission. Group based filtered OFDM will be a good candidate, which is easy to be integrated with SCMA and provides much better localized spectrum than traditional OFDM.
The prototype system is built with the soft baseband concept, namely that all the baseband processing is done by CPU instead of FPGA/DSP. At the base station side, one server (Huawei Tecal RH2288) is responsible for all the baseband processing, to which standard commercial radio frequency components (Huawei product RRU3232) are connected. At the user side, the CPU of 1 laptop (MacBook Pro ME294CH/A) is used to model the processing of 2 users’ baseband, which then connects to 2 mobile RF modules developed by us. A user interface (UI) is developed to shown the real-time throughput of each UE, supporting also the real time change of user status and system operation modes.

Abstract: Relaxed synchronization and access to fragmented spectrum are considered for 5th generation of wireless cellular networks. Frequency Division Multiple Access for Filter Bank Multicarrier (FBMC) modulation provides promising performance without strict synchronization requirements contrary to conventional Orthogonal Frequency Division Multiplexing.
The demonstration will highlight the advantages of FBMC compared to OFDM in the context of fragmented spectrum and asynchronous multiuser access for the uplink of beyond 4G systems. This work is part of the European 5GNOW project (www.5gnow.eu), which is questioning the design targets of LTE and LTE-Advanced and the obedience to strict synchronism and orthogonality.
We plan to present a reconfigurable FPGA/ARM digital baseband hardware platform implementing fragmented spectrum processing both at transmit and receive parts using FBMC modulation and aiming at demonstrating the FBMC built-in filtering feature adapted to spectrum availability in the fragmented case. The proposed multi-user receiver architecture based on frequency domain processing combined with the fair frequency localization of the FBMC prototype filter provides an architecture that allows for more efficient multiuser asynchronous reception compared to OFDM. The objective of the demonstration is thus to prove the feasibility of FBMC multiuser access (FBMC-MA) in a multiuser asynchronous environment.
The setup will be composed of two user equipments (transmitters) and one receiver (acting as a base station). Real time transmission will be done through RF front ends at 2.7GHz via the National Instrument NI PXIe-1062 equipment. The application running on top of the physical layer is uplink video conference service and we demonstrate the robustness of FBMC compared to OFDM in the case of timing misalignment between the two user equipments (multi-user asynchronous access).
The multiuser receiver architecture has been implemented on a Xilinx Kintex-7 (XC7K325T) FPGA of a custom-based platform developed by CEA-Leti.

Abstract: Through the availability of large contiguous bandwidths and the resulting applicability of simple air interfaces without complex and expensive techniques for optimized spectrum utilization, the use of mmWave spectrum presents an exciting option for the huge traffic demand expected in future wireless 5G networks. With the small wavelength large antenna arrays become feasible with strong directional gains that easily compensate for the higher pathloss in frequencies of 30 GHz and above, and allow for a deployment of cellular access networks in dense urban outdoor scenarios.
The SW demo proposed for presentation in the Globecom Industrial Demo track shows such a deployment scenario in a live interactive radio simulation of a 5G enhanced Local Area network with a mmWave propagation and channel model aligned with real-world measurements.

Abstract: Application scenarios, such as Internet of Things, Gigabit wireless connectivity, tactile Internet, and many more, expected for the fifth generation (5G) of cellular communication systems reveal major shortcomings of LTE/LTE-A. Tremendous efforts must be spent to collect the gains and to manage such systems under the premise of strict synchronism and orthogonality.
The advent of the Digital Agenda and the introduction of carrier aggregation are forcing the transmission systems to deal with fragmented spectrum. Moreover, the fraction of machine-type-communications (MTC) is growing fast. In fact, the massive wireless connectivity of machines with other machines, referred to as M2M or the Internet of Things (IoT), is the next foreseen killer application. Such sporadic
traffic generating devices (e.g., MTC devices in the IoT) should not be forced to be integrated into the bulky synchronization procedure of LTE-A PHY layer random access. Given these requirements, it is widely accepted that new 5G air interfaces are needed.
A new waveform approach “Universal Filtered Multi-Carrier” (UFMC), also known as UF-OFDM, being better suited for 5G has been invented by Bell Labs. The new waveform supports reduced interference between synchronous and asynchronous traffic. This allows for efficient transportation of small packet services, reducing signaling overhead and battery consumption.
Furthermore, UFMC delivers a significant spectral side lobe level reduction, which allows handling very heterogeneous services (from ultra-broadband to small packets) in the same frequency band in a flexible and scalable manner.
A live demonstration of synchronous and asynchronous traffic will be presented and compared with OFDM. A high speed Video with synchronous broadband traffic and an application with an asynchronous MTC application will be shown simultaneously, using the UFMC waveform. To visualize the big advantages of UFMC, the same scenario will be shown with OFDM to have a direct comparison.
Additional poster material provides the context of Bell Labs’ vision and benefits on a new 5G air interface design.

ID-22: Title: Noise Figure Measurement with National Instruments RF Platform
Track: Enabling Technologies
Presentation: 2:20-2:40 pm

Abstract: One key figure of merit for a receiver is sensitivity, or the ability to detect low-magnitude signals. Receiver sensitivity is limited by the intrinsic noise present in the device itself, which for the amplifiers and mixers present in a receiver signal chain, is characterized by noise figure. Noise figure measurements are commonly performed upon amplifiers and other active devices during design, but typically not performed during production due to the additional test station equipment cost, as well as the additional, usually long, test times involved. Noise figure meters are a class of RF instrumentation dedicated to noise figure measurements, but a vector signal analyzer (VSA) and complementary system low-noise amplifier (LNA) can be used to perform these same noise figure measurements, reusing equipment typically already in place for an RF test station, while taking advantage of the fast measurement speeds of NI's world class RF analyzers. This presentation will provide a brief background of various noise figure measurement techniques, and discuss their implementation with the NI RF platform. In recent years, numerous improvements have been made in noise figure measurements through better algorithmic understanding of the measurements, analyzers with better sensitivity performance, and less error-prone methods of processing noise power measurements. The complementary demo will focus on noise figure measurement using the Y-factor method.

ID-23: A Versatile, Reprogrammable IEEE 802.11ac FPGA Implementation for Wireless R&D
Track: Access Technologies
Presentation: 2:40-3:00 pm
Authors: Robert Daniels robert.daniels@kumasignals.com United States Kuma Signals, LLC
Abstract: Commodity RF test equipment transceivers with full link configurability and stable, general purpose computing platform interfaces, as best demonstrated by Ettus' universal sofware radio peripheral (USRP), have recently become available. These products have eliminated an electromagnetic spectrum exploitation barrier that previously existed for academic and research institutions, small businesses, and organizations with limited wireless research and development (R&D) budgets or short R&D project time constraints. The design and over-the-air testing of new wireless physical-layer algorithms and protocols is no longer restricted to organizations that are willing to invest in large, long-term projects to create the necessary equipment and software infrastructure.
Despite the transformation of the wireless research and development (R&D), certain barriers still exist for cost-effective, quick-and-easy wireless link R&D. Part of the advantage of the aforementioned commodity test equipment platforms, high configurability and convenient high-level programming on general purpose platforms, also limits certain R&D capabilities. In particular, two aspects of broadband wireless transceiver design (e.g., WiFi, LTE, etc.) require low-level implementation: medium access control (MAC) protocol testing and physical layer implementation complexity/feasibility evaluation. General purpose computing platforms simply cannot, in general, execute physical layer signal processing and data handling fast enough to meet latency constraints imposed by industry standards. Furthermore, physical-layer algorithm implementation in higher-level languages cannot be easily translated to DSP, FPGA, or ASIC hardware where fielded designs reside. A solution is needed to provide the advantages of the aforementioned commodity test equipment, but with the addition of easily-configurable low-level implementations.
This demonstration presents an IEEE 802.11ac wireless link with all physical layer baseband transceiver processing entirely contained on a Xilinx Kintex 7 FPGA. All components of a modern wireless link are included: forward error correction, bit interleaving, QAM constellations, OFDM modulation, synchronization (packet detection, timing, frequency offset compensation, channel estimation), equalization, pilot phase tracking, and Viterbi decoding of frames. The FPGA source is easily adapted and extended because it is entirely defined within the National Instruments (NI) LabVIEW FPGA development environment on general purpose computing platforms. Low latency MAC testing is quickly enabled through an application programming interface (API) that already provides CRC-32 processing, data acknowledgements, and link configuration (e.g., bandwidth, modulation, coding, etc.). LabVIEW FPGA also drastically shortens the FPGA programming learning curve through graphical programming and drag-and-drop access to large library resources. In addition, RF and analog hardware configuration requires very little domain knowledge thanks to software instrument representations and plug-and-play NI PXI hardware drivers. In short, this demonstration will showcase software components integrated with a simple-to-use, cost-effective NI hardware platform, that provide quick-and-easy, over-the-air wireless R&D on all layers for intelligent innovation of today's cutting-edge wireless standards.

Abstract: Worldwide adoption of mobile phones with new technologies such as NFC embedded in them has seen an increasing upward trend. Chipset manufacturers are releasing multi standard all inclusive chips with 802.11ac, Bluetooth, GPS, FM & NFC to enable this trend. Until recently, NFC enabled mobile phones which were used for personal communications and media players have seen this trend of being used as a payment ,ticketing & connection initiator devices. According to research estimates, wireless attach rates for NFC are being predicted at greater than five billion units in the next few years.NFC RF Analog testing plays a pivotal role in shaping the future of this adoption trend. For Mobile Devices NFC Analog testing, the need of the hour is a minimal footprint, modular, faster and open software test architecture which allows for all technologies 802.11ac, Bluetooth, GPS, FM & NFC to be tested. NI has recently worked on a NFC Analog Test Framework, which will be discussed highlighting how signal processing principles can be applied for all tests as defined by NFC Forum.
We discuss the implementation of the NFC Forum related Signal Generation APIs and Signal Analysis APIs which cover the various Scenarios such as Power Reception, Carrier Frequency & Modulation Polling to Listening Device.

Abstract: One major factor in calculating the total cost of test is test times. This demo will demonstrate improved RF power amplifier test times by utilizing 2 technologies 1) co-processing and 2) FPGA-based power servo.
A test solution typically consists of an instrument to acquire data and a processor to compute measurements. The processing involved in some measurements like LTE RF standard is huge and can overload the processor. In such scenarios, a possible solution is to utilize multiple threads of a multi-core processor. The co-processing technique using PXImc further extends a processor's capability by adding a second processor.
The NI PXIe-5644R Vector Signal Transceiver (VST) combines the features of a VSA, a VSG, and a user-programmable FPGA. Power servo is a big portion of a power amplifier test plan. The combination of VSA, VSG and FPGA allows for power servo that is FPGA-based which is much faster compared to traditional power servo methods.
In this demo, we will show some typical power amplifier measurements. We will then show an improvement in test times by using co-processing and FPGA-based power servo.

ID-26: Title: G.fast Transceivers with 16-port Vectoring
Track: Enabling Technologies
Presentation: 4:20-4:40 pm
Authors:
Rami Verbin rami@sckipio.com Israel Sckipio Technologies
Abstract: In December the ITU-T is going to approve a new communications standard, G.9701 - also known as G.fast. This new broadband standard is designed to deliver ultra broadband performance over short copper lines, up to 400m, shorter than traditional xDSL. Using a spectrum of 2-106Mhz, the G.fast transceivers are designed to deliver up to 1Gbps. The G.fast technology allows the telephone companies to enhance their broadband services avoiding the need to deploy fiber all the way to the customer’s house. The result is lower CAPEX and much faster return on investment.
The existing copper pairs were never planned for use up to 106MHz. The result is very high cross-talk between the different lines in the binder. This cross-talk may in some cases be even higher than the signal level received over the direct channel. To be able to support the very high target bit-rates, G.fast is implementing cross-talk cancellation scheme known as “vectoring”. Implementing vectoring over large number of ports, very wide bandwidth and high cross-talk is a challenging task. The channel matrix in the higher frequencies is typically bad conditioned which makes it even harder to invert. Furthermore, the wide bandwidth and the large number of ofdm carriers results in tough HW requirements from number of different aspects, i.e., processing power, memory size and high speed communication needed for exchanging information between the different ports.
The main goal of the demonstration is to prove the viability of G.fast modems in a real-world environment. The demonstration will include 16 consumer premises equipment (CPE) devices (essentially G.fast to Ethernet bridges) connected to a single 16-port DPU device via a 50 meter CAT-3/0.5mm binder. The DPU device is using four 4-port G.fast chipsets exchanging high speed information between them to implemented vectoring internally, without a need for any additional hardware. Performance with and without vectoring will be demonstrated to indicate the effectiveness of the cross-talk mitigation scheme.

Abstract: Aeroflex Test Solutions is a global leader in the Test and Measurement Instrumentation marketplace. Our technologies and product range cover all stages of product developments including functional validation, field trials, system capacity and stability, and production tests. New developments of all major wireless standards are timely updated. In addition, many of our designs are to meet customer’s requirements in pre-standardisation.
Aeroflex TM500 test mobiles have been widely used by mobile base station manufactures to test most of up-to-date features in cellular communication standards. TM500 test mobiles are designed in a modular structure. It is not only a platform for air interface but also a simulator for a whole cellular system. In the demonstration, we show the following new features in our TM500 products:
• 5G candidate air interface: Filter-Bank Multi-Carrier (FBMC) techniques are considered as a candidate for 5G air interface. FBMC air interface based on isotropic orthogonal transform algorithm (IOTA) has been developed and prototyped in our TM500 platform. The design of new Physical Layer protocol has been borrowed from the long term evolution (LTE) frame structure. We carry out comparison and show the advantages of FBMC over traditional OFDM in terms of throughput utilisation and frequency error sensitivity.
• Interference cancelation techniques for 4G: Moving the tests of cell-edge users from homogeneous network toward Heterogeneous network (HetNet) would be challenging. Due to the availability of pico-cells deployed inside a heavy traffic macro-cell in HetNet, transmissions for some users can be offloaded to pico-cells. In HetNet, high interference from macro-cell may cause problem to pico-cell cell-edge users. LTE-A Release 10 and latter allow users in multiple pico-cell to share some subframes without interference of data signals from the macro-cells (known as FeICIC in LTE Advanced). However, reference and synchronisation signals transmitted by the macro-cells still cause interference. We present the techniques to mitigate: i) the interference of reference signal from the macro cell in decoding signals from a pico-cell and ii) the interference of synchronisation signals from the macro-cells in detecting a new pico-cell.
• Multi-User Mobility Model: The multi-user version of TM500 allows testing base stations in system perspective. TM500 simulates multiple users in different channel conditions and acts as an entire multi-user cellular network environment in working with a base station or group of multiple base stations. The tests supported by TM500 can help the base station manufacturers and operators to see the efficiency of the base stations including hand over, resource allocation, and multi-cell cooperation. This infrastructure test solution will be presented in the demonstration.
These features are carefully designed with practical constraints. The implementation process includes technical feasibility, MATLAB simulations, DSP implementation, and test and verification.

Abstract: Full duplex has emerged as a new breakthrough in wireless communication, thus attracted significant attention both from academia and industry. It theoretically should be very simple to accomplish. Most prior work on full duplex radios has assumed that self-interference cancellation (SIC) is perfectly operated. In practice, however, SIC has been a critical issue to implement full duplex radios in a real wireless environment. We describe the main goals of the demo to overcome this issue. First, we implement an RF front-end that can provide SIC>60dB with a combination of antenna and RF SIC. The TX signal from PA is injected to a rat race coupler (180 degree hybrid) and radiate through the antennas (TX1 and TX2). Since the TX signals at TX1 and TX2 are out of phase by 180 degree, they are cancelled at the RX antenna located at the middle of TX1 and TX2. This antenna SIC may not be enough and the TX signal still remains the RX path. The remaining TX self-interference is further cancelled at the LNA balun using the tapped TX signal from a directional coupler. The LNA balun needs to be carefully designed to provide SIC with a minimal RX path loss and matched port impedance. By measuring s-parameter of the three antennas, we can find the antenna SIC level and delay of the remaining TX signal at the RX port. The variable and delay unit will be designed to compensate the antenna SIC level and delay of the remaining TX signal. Second, we also demonstrate digital band SIC cancellation algorithms in addition to implementing modules of wireless standard. We design a full duplex system that is capable of supporting the LTE with wide bandwidth (>20MHz) and 20dBm (or higher) average TX power. In the Industrial Demos Session, we aim at realizing a testbed for showcasing an in-band full duplex radio system that can simultaneously transmit and receive on the same frequency and time resource band using PXIe products by National Instruments.
