Description: 仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。-Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.

Description: 该课题是基于MATLAB平台的图像去雾处理，配备一个人机交互GUI界面，可以选择局部直方图均衡化，全局直方图均衡化，Retinex算法，通过对比处理前、后的图像的直方图，而直方图是一副图像各灰度值在0-256的分布个数的表，信息论已经整明，具有均匀分布直方图的图像，其信息量是最大的。
二、算法介绍
①全局直方图均衡化：通俗地理解就是，不管三七二十一，直接强行对彩色图像的R,G,B三通道颜色进行histeq均衡处理，然后进行三通道重组；
②局部直方图均衡化：设置一个固定大小的滑块，分别对彩色图像进行R,G,B三通道进行逐个像素地平滑处理，然后重组三通道，当然这样做的，虽然实现了图像的去雾效果，但是以部分像素曝光作为牺牲补偿。
③Retinex算法：通俗地讲就是，分离R,G,B三通道，对每个通道进行卷积滤波。(This project is based on MATLAB platform image defogging processing, equipped with a human-computer interactive GUI interface, you can choose local histogram equalization, global histogram equalization, Retinex algorithm, by comparing the histogram of the image before and after processing, and the histogram is a table of the number of gray value distribution in 0-256, information theory has been clear, with uniform distribution histogram Image, its information is the largest.)
