说明：  该文件包含了8psk调制信号的产生，以及经过多径瑞利信道后，前后对比的星座图，经过CMA均衡算法后输出信号，能对均衡算法有更深的认识。
(This file contains the generated 8psk modulation signal and multipath Rayleigh channel after, before and after the constellation, after CMA equalization algorithm output signal, capable of balancing algorithms have a better understanding.)
