真是基于matlab的QPSK，格雷码，瑞利衰减信道，加性高斯白噪声仿真-Really based on matlab QPSK, Gray code, Rayleigh fading channel additive white Gaussian noise simulation

QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比-Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, resp

考虑载波的qpsk信号在瑞利信道上的仿真 可以下载学习-Considering on the QPSK signal of the carrier in Rayleigh channel simulation can download the study
