摘要
本文用Matlab仿真通信系统的四相相移键控（QPSK）调制及相关解调，分析数字信号在AWGN信道和Rayleigh衰落信道巾的传输。仿真实现在AWGN信道与Rayleigh信道下的传输差错特性，包括仿真的结果与理论计算的结果。
In this paper, Matlab simulation of communication systems related to demodulation of QPSK modulation and analysis of digital signal in the AWGN channel and Rayleigh fading channel transmission. Simulation of the AWGN channel and Rayleigh channel of transmission error characteristics, including the simulation results with the theoretical results.
