Abstract

The paper studies the processing technique of different channels in SDR (software defined radio). The key technique is to design digital filters of different frequency bands to receive the information of different channels. The method of SDR channel process based on FPGA is proposed and compared to traditional DSP method and algorithm. Based on founding the model of SDR channel processing, the distributed algorithm for FPGA is stated in detail and the block diagram of the algorithm achievement in FPGA is gotten out. It is believed that the FPGA method is better than DSP on speed and performance in this study.
