使用c语言，是随机信号分析教科书的实验程序合集，是正确的。(Using the c language, is a random signal analysis of the experimental procedure textbook collection, is correct.)

此程序为用matlab编写的水平方向上的帧内预测程序，预测对象为4*4像素块(horizental intra prediction)

this program is about pulse propagation in fiber

采用了小波去噪的思想，独立成分分析算法降低原始数据噪声，一个师兄的毕设。( Using wavelet denoising thought, Independent component analysis algorithm reduces the raw data noise, A complete set of brothers.)

本源代码首先实现普通的直方图均衡化，再实现灰度级之间的均匀分布，可以有效的解决直方图均衡化过程中的灰度断层现象。使得图像更加的柔和，直方图分布更均匀。(Source code first to achieve common histogram equalization, and then to achieve uniform distribution between gray levels can be an effective solution in the process of histogram equalization, gray fault phenomenon. Makes the image more of the soft histogram more evenly distributed.)

说明：  ＥＭＤ经验模式分解，提取复杂信号的基本模式分量(EMD EMD to extract the basic pattern of components of complex signals)

本程序包里面代码用matlab编写，有三个demo，分别处理然后用CS重建1维，2维信号，最后一个是对大脑图像做CS重建对比(This package inside the code written in matlab, there are three the demo, be treated separately and then use the CS reconstruction of one-dimensional, two-dimensional signal, the last CS reconstruction compared brain images)

基于周期失配序列和m序列的OFDM信道估计性能比较(Mismatch sequence and m-sequence OFDM channel estimation performance comparison)

简单明了的光束传播方法，计算自由空间光传播，使用FFT算法，在matlab中简单实现。(two step beam propagation method with FFT)

本例程为matlab实现的单径或多径瑞利衰落信道仿真的几种例程(Matlab routines for the realization of the single-track trails or Rayleigh fading channel simulation of several routines)
