Software Defined Radio and Prototyping Platforms for Next-Generation Wireless Systems

Abstract - This presentation will give an introduction to software defined radio (SDR) and two prototyping platforms in the context of 3G and 4G (e.g., WiFi and LTE): model-based design tools for PC development (GNU Radio) and model-based design tools for FPGA Development (System Generator). It will also include

an overview of mixed architecture and how the FPGA can be leveraged to offload the CPU. The talk will contain an illustrative use case of an FPGA implementation of a polyphase channelizer for GSM/EDGE and an FPGA OFDM Physical Layer (802.11a) controlled from GNU Radio. The second part of the talk will investigate how SDR concepts can be extended to support prototyping in the context of 5G (Massive MIMO). RF upgradability with millimeter wave support and replaceable radio heads are mandatory to accommodate growth to 5G. Massive numbers of RF channels (100x100 or more) together with over-the-air bandwidth requirements of up to 250 MHz per antenna leads to channel aggregation bottleneck in traditional

systems architecture. A new architecture and 5G Massive MIMO tested, with scalable central processing engine comprised of distributed FPGA clusters, and based on advanced telecom industry standards (ATCA, MicroTCA, FMC) will be presented. The demonstration part of this presentation uses Software Defined Radio (SDR) platforms, including the new PicoSDR device that has internal MIMO transceivers (2x2 or 4x4) with a 28 MHz bandwidth each and a tuning range of 300 MHz to 3.8 GHz, and the PicoDigitizer that uses external wideband (100/200 MHz) receivers with a tuning range of 100 kHz up to 8/20/30 GHz and phase coherency for beam forming (1, up to 8, and up to 16 elements configurations).

Tristan Martin has a bachelor degree in electrical engineering and a master degree in computer engineering. He has gained experience in the past working for CAE Inc. as a System Software Specialist, where he worked on requirements management, design, development, integration, deployment, and update of digital audio technologies and simulation software products. He was also responsible of environmental acoustics recording and data gathering on military aircraft, sound and vibration data analysis, modeling, and re-synthesis. He is currently a technical expert in tailoring Nutaq's FPGA- and CPU-based solutions and providing system architecture guidance to end customers in the early phase of their projects for some of the world's most demanding military and scientific applications. He is enthusiastic about process improvement, the Software Defined Radio (SDR) user community, and is a C++ programmer in his spare time. He provides Nutaq's clients with a strong customer focus and a high ability to synthesize information.

Moti Ahmed is with AgileAccessT, Flemington, NJ. His

early career is in video, in particular systems integration, maintenance, and

restoration of broadcast video equipment. Later, he joined RCA Somerville,

New Jersey, as a Test Engineer, where he developed hardware interfaces, test fixtures

writing software for ATE, for production testing of Video LSI. He moved

to IC Design within RCA, where he developed several video signal processing

chips for Catalog and Custom. His wireless career began at BL Reading, PA, where he got involved in exploratory chip-set design for the GSM Standard. Later, he moved to the

Wireless Radio Group in Whippany, NJ, where he investigated radio architectures and design methods for high performance radio receivers for base Stations. Other independent activities included fiber-optic wireless carrier transport, and network components for Distributed Antenna Systems (DAS). He is currently an independent consultant. Among others, he supports LTE eNB radio hardware development, and eNB hardware integration and testing. His current interests include Software Definable Radio (SDR), millimeter-wave technology tracking, and FPGA Programming.
