Nowadays, the higher frequency increases difficulty to implement full-digital receivers, a high-speed full-digital DS-CDMA receiver has been designed based on FPGA in the paper, meanwhile, traditional digital system is improved by adopting the idea of high-speed digital system, and the PN module is implemented in a new way, moreover, the effect of despread-demodulator for direct-sequence spread-spectrum system on high-speed and low-occupation system is introduced, also the method of omitting filter under certain conditions is given, in the end, the simulation and experiment results are presented.
