| Abstract: | This paper centers the design and implementation of short-wave multi-channel parallel processing system based on software defined Radio,for the demand of the short-wave narrow band signal real-time processing.The board applies four DSP chips which has the high performance-cost ratio to process four channel parallel signals realtimely and a high-powered FPGA to controll and co-process the system,and the system can be programmed and configured repeatly.Then,the paper develops the programs of FPGA and host,and implements a demodulation algorithm based on DSP.In the end,a practical application example of the system in software defined radio receiveing system is provided,and practice proves that the system has good performance and flexibility. |
