中文说明：
给出比较少见的16PSK的仿真算法，包括高斯信道，瑞利信道及线性时不变信道。其中，在瑞利信道中，给出了均衡前均衡后比较结果，从中可以看出均衡的效果。
English Description：
The simulation algorithm of 16PSK is given, including Gaussian channel, Rayleigh channel and linear time invariant channel. Among them, in Rayleigh channel, the comparison results before and after equalization are given, from which the effect of equalization can be seen
