“…Font-Bach's work [46] compares hardware implementations and coexistence capabilities of PPN-FBMC and LTE OFDM transmitters using the Xilinx ZC706 FPGA and Analog Devices FMCOMMS 3 AD9361 SDR front end, for the application of SU access to PMR bands (Professional Mobile Radio). Drozdenko presents an 802.11a SDR-WiFi implementation targeted to the same hardware in [47], [48], [49], [50], using the MathWorks Model-Based Design workflow for SDR targeting featured in this paper. The only other publications discovered that make use of the workflow are by Dang [51] and Cai [52], which review the QPSK transmitter/ receiver examples created by MathWorks engineers to demonstrate their tools [53][54] [55].…”

This paper presents the research carried out in developing and targeting a novel real-time Dynamic Spectrum Access (DSA) Frequency Spread Filter Bank Multicarrier (FS-FBMC) transmitter prototype to programmable 'ZynqSDR' Software Defined Radio (SDR) hardware, and introduces a series of experiments used to validate the design's 'cognitive' DSA capabilities. This transmitter is a proof of concept, that uses DSA techniques to enable Secondary Users (SUs) to access the band traditionally used for FM Radio broadcasting (88-108 MHz), and establish data communication channels in vacant parts of the FM Radio Primary User (PU) spectrum using a multicarrier modulation scheme with a Non Contiguous (NC) channel mask. Once implemented on the hardware, the transmitter is subjected to various FM Radio environments sampled from around Central Scotland, and it is demonstrated that it can dynamically adapt its NC transmitter mask in real time to protect the FM Radio signals it detects. A video is presented of this dynamic on-hardware spectral reconfiguration, and the reader is encouraged to view the video to appreciate the responsiveness of the design. An investigation into potential FBMC guardband sizes is carried out, with initial findings indicating a guardband of 200 kHz (either side of an FM Radio station) is required in order to prevent interference with the PUs. This paper also demonstrates the capabilities of the MATLAB R / Simulink R Model Based Design ZynqSDR workflow, and provides a case study and reference design that we feel other researchers working in this field can benefit from.

“…There is much interest in the research community around the effective design of SDR systems, in particular the joint programmable hardware/ software co-design of such systems. For instance, researchers in [24] discuss their approach to an SDR design, based on the Analog Devices FMCOMMS3, ZedBoard / ZC706, and MathWorks and Xilinx software tools. Other studies have investigated the potential of dynamic partial reconfiguration techniques for implementing flexible SDRs [25].…”

The availability of commercial Radio Frequency System on Chip (RFSoC) devices brings new possibilities for implementing Software Defined Radio (SDR) systems. Such systems are of increasing interest given the pace of innovation in wireless technology, and the pressure on RF spectrum resources, leading to a growing need to access the spectrum in more dynamic and innovative ways. In this paper, we present an SDR demonstration system based on the Xilinx RFSoC platform, which leverages the Pythonbased 'PYNQ' (Python Productivity for Zynq) software framework. In doing so, we highlight features that can be extremely useful for prototyping radio system design. Notably, our developed system features Python-based control of hardware processing blocks and Radio Frequency (RF) data converters, as well as direct visualisation of communications signals captured within the chip. The system architecture is reviewed, hardware and software components are discussed, functionality is demonstrated, and aspects of the system's performance are evaluated. Finally, it is noted that this combined RFSoC + PYNQ approach is readily extensible for other SDR systems; we highlight our online shared resources, and invite other engineers to investigate and build upon our work.
