Description: 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(加性高斯白噪声信道)信道(AWGN信道：不考虑通信信道信号时，由宽频范围描述的统计随机无线噪声。)。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, channel for AWGN (additive white Gaussian noise channel) channel (AWGN channel: do not consider communication channel signals, described by the scope of broadband wireless random statistical noise.). 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. Platform: |
