摘要：

sPerformance of DS-CDMA system with M-ary orthogonal modulation is investigated, through computer experiments and mathematical analysis we find the variance of multiple access interference(MAI) in synchronous AWGN channel should be twice as much as those adopted in previous reference. System performance of successive interference cancellation in multipath Rayleigh fading channel is also investigated by means of simulation. Our results show that successive interference cancellation is a simple yet effective way to mitigate MAI when the user density is low.
