香农编码源程序 如：p=[0.4 0.3 0.2 0.1] shannon(p)(shannon source code)

MATLAB实现的QAM调制与解调源代码 (matlab，QAM modulation)

根据所点击选择的三个点，进行自动画圆的程序。(Click to select the three points, the program automatically draw a circle.)

说明：  数字通信塔，用增量调制将模拟信号转换为离散的数字信号，在基带中采用Miller码编码，信道编码采用汉明码，调制方式采用PSK,通过AWGN信道传输。(A digital communication system，PCM encoding converts analog signals into discrete digital signal, uses Miller code coding in baseband and Hamming code in channel coding , then PSK modulation way )

用Matlab对LMS算法的实现,可用于时延估计，滤波器等方面。(LMS algorithm)

DES加密算法 matlab版本。 DES全称为Data Encryption Standard，即数据加密标准，是一种使用密钥加密的块算法，1976年被美国联邦政府的国家标准局确定为联邦资料处理标准（FIPS），随后在国际上广泛流传开来。(DES encryption algorithm matlab version. DES called the Data Encryption Standard, Data Encryption Standard, is a key block encryption algorithm, 1976 National Bureau of Standards has been determined for US federal government Federal Information Processing Standards (FIPS), then widely spread in the world come.)

本帖调用自编函数（grating）绘制光栅条纹图像，通过例子讲解水平、竖直、环状和辐射状光栅条纹图像的绘制，用黑白和彩色显示效果给大家视觉上的震撼。调用自编函数时，可以通过成对出现的参数控制条纹的方向、颜色、周期、相位角等。(This post calls self-function (grating) draw grating image, by way of example to explain the horizontal, vertical, circular and radial grating image rendering, with monochrome and color display give you visual shock. Self function call, the parameters can be controlled by pairs stripe orientation, color, period, phase angle.)
