一个四用户的扩频通信系统,扩频增益为N=16,采用Walsh码进行直接序列扩频,BPSK调制,无线信道为AWGN信道。在接收端进行解扩,解调,判决,通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)
