4psk&8psk的matlab实现，采用蒙特卡罗仿真法，计算误码率误比特率，绘制相应曲线(the realization of 4psk&8psk by Matlab tool,it use Monte Carlo way to calculate the BER and draw the graph.)

国外经典书籍MULTIVARIABLE FEEDBACK CONTROL-多变量反馈控制 的源码，是学习多变量反馈控制必不可少的Matlab源码！(Foreign classic books MULTIVARIABLE FEEDBACK CONTROL-multi-variable feedback control of the source code is studying multivariable feedback control essential Matlab source code!)

声波中计算入射波、反射波系数，拟合出图像(failed to translate)

对比各种小波变换的效果，B为输入的原始数据，需要自己添加数据并设置为B(Comparative effects of various wavelet transform, B is the input original data, and the data they need to be added to B)
