Abstract
This chapter presents an FPGA-based SDR platform which serves as a proof-of-concept for cognitive radio techniques. The platform is based on a fully reconfigurable hardware and operates as a 12.8 Mbps RF-to-Ethernet bridge in the Industrial, Scientific, and Medical (ISM) bands of 868 MHz and 2.45 GHz. The data-processing algorithms of the platform are implemented in an FPGA using Xilinx’s System Generator rapid prototyping tool. A MicroBlaze processor is also included to control the dynamic partial reconfiguration of the FPGA for small in-band frequency changes. In order to achieve full-band reconfiguration, a commercial RF front-end and a custom reconfigurable antenna are integrated. Design and implementation details are presented, along with measurement results.
