线性调频信号的功率，采用MATLAB的强大的自制函数(Linear FM signal power, using MATLAB' s powerful home-made function)

说明：  对图像形态学膨胀腐蚀运算，可以有效提取边缘。并有很强的抗噪能力。(Morphological dilation and erosion operations on images, you can effectively extract the edge. And have strong anti-noise ability.)

说明：  Matlab编写BPSK信号通过AWGN信道的仿真过程(Matlab write BPSK AWGN channel signal through the simulation process)

说明：  仿射变换和猫脸变换是图像加密算法中最基本的算法之一，很多重要的加密算法都是在此基础发展而成的，该程序供研究加密算法的初学者参考使用。(Affine transformation and cats face is the most basic image encryption algorithm in one of many important cryptographic algorithms are evolved on this basis, the program for research reference for beginners to use encryption algorithms.)

统计稀疏分解（SSDP）欠定盲分离MATLAB仿真程序。能在接收天线个数小于源信号个数时，仅仅利用观察信号恢复出源信号。(Statistics sparse decomposition (SSDP) underdetermined blind separation of MATLAB simulation program. In the number of receiving antennas is less than the number of source signals, using only the observed signal to recover the source signals.)

matlab实现通信系统中信道的仿真，其中包含了最基本的matlab产生各种信道的代码，并有详细的说明(matlab simulation of communication systems the channel, which contains the most basic of matlab code to generate a variety of channels, and a detailed description of)

这是一个用于计算物理的，用于画电势分布的m文件，能把一个电场画出来(This is a used to calculate the physics, used to draw the potential distribution m file, can draw an electric field)
