说明：  两个matlab的GUI实现UDP通讯，建议在两台电脑上测试。(The two matlab GUIs implement UDP communication. It is recommended to test on two computers.)

LDPC码的完整的编译码，包含特征值与特征向量的提取、训练样本以及最后的识别，对HARQ系统的吞吐量分析，基于分段非线性权重值的Pso算法，最终的权值矩阵就是滤波器的系数，matlab小波分析程序。

用MATLAB程序，实现了在空域下，对图片的亮度值写入秘密信息的程序，很有参考价值(With the MATLAB program, implemented in the airspace, the brightness value of the picture written procedures for confidential information)

该算法明确描述了量子遗传算法的实现流程，通过运行，该程序是正确的。(The algorithm clearly describes the realization of the quantum genetic algorithm process, by running the program is correct.)

matlab的一些最基本的应用(Matlab some of the most basic )

线性系统的校正方法，各种矫正方法都有涉及(Linear Systems correction method, various correction methods have involved)

细化算法，对图像转化二值图像后，对高亮部分细化之几个像素，适用于道路提取，某物体骨架提取，线路提取等领域(After the image is transformed to two value images, a few pixels of the highlighting part are applied to the extraction of road, the extraction of an object skeleton, the extraction of line and so on.)

本程序功能为实现基于压缩感知的数字图像水印算法，主要包括水印嵌入、水印提取及子程序三大部分。水印载体图像和原水印图像使用者可以自行更改。(This program functions for the realization of compression based digital image watermarking algorithm, including watermark embedding, watermark extraction and subroutines three major parts. The watermark carrier image and the original watermark image can be changed by the user.)
