基于反相对称法的CDMA通信方式仿真研究

Simulation of CDMA communication mode based on phase-inversion symmetric method

通过理论分析和仿真,证实了将反相对称法用于CDMA通信系统可使误码率减小,在信噪比为-5dB的情况下误码率约降低为原来的3%,证实了基于反相对称法的CDMA通信方式的优越性。

Through the theoretical analysis and simulation,this paper shows the SNR（signal-to-noise ratio） is-5dB,the BER（bit error rate） of CDMA communications mode based on phase-inversion symmetric method（PISM-CDMA） is lower nearly 30 times than traditional CDMA communication mode,and confirms the superiority of PISM-CDMA communication system.
