The design of wide-band digital transceiver based on FDM signal is introduced. The detailed hardware realization and software processing flow of the system based on software radio theory is proposed, and the efficient realization method of the parallel FIR filter and parallel CIC filter based on FPGA platform is described. The simulation and testing results of the wide-band digital transceiver is derived. Meanwhile it has features of simple hardware structure, low logical resource requirement and strong generalization and expansibility.
