4种LDPC的译码算法比较，经测试可以运行。(4 kinds different ldpc decoding algorithm-nomalized/offset/MS and SP )

说明：  数字滤波器的几个仿真代码，大家先看看，不知是否有用(Digital Filter Matlab Simulation)

function Px=overlay(N,omega,A,sigma,num) OVERLAY Forms multiple power spectral density estimates. ------- USAGE Px=overlay(N,omega,A,sigma,num) Calculates the periodogram using an ensemble of realizations of a process consisting of a sum of complex exponential in white noise. N : length of the signal omega : vector containing the sinusoid frequencies A : vector containing the sinusoid frequencies sigma : the variance of the white noise num : size of the ensemble (number of periodograms)

本程序实现对图像的打开、退出操作，以及图像旋转、添加噪声、图像平滑（椒盐噪声处理、均值低通滤波处理、中值滤波处理）、图像直方图显示、预测编码，在MATLAB中用GUI实现。(This program implements the image is opened, quit the operation, as well as image rotation, adding noise, image smoothing (salt and pepper noise processing, the mean low-pass filtering, median filtering process), histogram display, predictive coding, in MATLAB using GUI implementation.)
