Cognitive radios require an intelligent MAC layer coupled with a flexible PHY layer. Most implementations use software defined radio platforms where the MAC and PHY are both implemented in software, but this can result in long processing latency, and makes advanced baseband processing unattainable. While FPGA based SDR platforms do exist, they are difficult to use, requiring significant engineering expertise, and adding dynamic behaviour is even more difficult. Modern hybrid FPGAs tightly couple an FPGA fabric with a capable embedded processor, allowing the baseband to be implemented in hardware, and the MAC in software. We demonstrate a platform that enables radio designers to build dynamic cognitive radios using the Xilinx Zynq with partial reconfiguration, enabling truly dynamic, low-power, high-performance cognitive radios with abstracted software control.
