Designment and Implementation of Cognitive Radio Model Based on FPGA
Cognitive radio (CR) is an emerging intelligence wireless communication technology now. In this paper, a new working platform model in the environment of CR has been put forward after the analysis had been finished based on the physical layer and the research of the physical layer had been done. First, a new communication model based on FPGA has been designed and a new algorithm of RFFE (RF Front End) model has been advanced. Then, performance analysis has been worked to this model. And last, FPGA is used for the host CPU in this model and DSP is used for the coprocessor to deal with the software and signals. Results show that the hardware monitor is enhanced and the throughput is improved, moreover, the system cost and the operating power are reduced in this model.
