Classification code Small in-class project good for matlab beginner thanks

基于MATLAB的数字均衡器 设计与实现 (MATLAB-based Design and Implementation of Digital Equalizer)

This is extention to my earlier code EgT binary -nitride. In this function , I have implemented the code for ternary nitride also.

说明：  IIR 滤波器，matlab实现，载频21.4MHz,带宽200KHz(IIR bandpass filter with matlab language,frequence of 21.4MHz,band of 200KHz)

QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )

Make the Huffman-tree from the lengths of the Huffman codes. The Huffman codes are also needed, and if they are known, they can be given as an extra input argument.

行程编码的matlab实现。编码后的图像存储在变量E中,该变量是一个三纬树组,前两纬表示起始像素的横、纵坐标，第三纬表示该行程的颜色值。(Matlab coding realize itinerary. Encoded image is stored in the variable E, the variable is a three-wai Tree Group, the former two-wai express start pixel horizontal, vertical coordinates, the third weft express the color values of the trip.)
