说明：  利用低通滤波器进行横条纹滤除，效果可以，最好进行一下后期处理，效果会更好。(Use of horizontal stripes of low pass filter filter, the effect can be desirable to look at post-processing, the effect will be better.)

利用维格纳方法实现对数字信号进行时频分析处理的功能(Wigner method implementation using digital signal processing functions time-frequency analysis)

对图片进行gamma校正，可以对黑白图片进行比较好的gamma校正，对彩色图片有一定得校正功效！(On the picture for gamma correction, black-and-white picture can be a better gamma correction, color picture of a certain efficacy of a correction!)

this is programm for propagation that can help you to solve the case in propagation and transmission media fron transmitter to receiver. we can count link budget in propagation.

基于循环统计量的Matlab程序，主要用于信号故障诊断(Circulation statistics based on Matlab program, mainly for the Signal Fault Diagnosis)
