MSK信号的模拟仿真代码。可以适合与研究MSK信号的人。(MSK signal simulation code. MSK signal can be suitable for people with research.)

获取对象骨架的方法，不同于matlab自带的bwmorph方法，但速度较慢(Access to the object skeleton methods, different from the matlab built-in bwmorph, but slower)

对于蜂窝移动通信的matlab仿真，实用性很强(For cellular mobile communication matlab simulation, very practical)

各种数字基带的调制调频,就是调幅啊，很简单的啊等等 (DSB modulation for sine signal，is it ok ,so easy.)

用matlab处理的人脸识别，基于pca算法(Matlab deal with face recognition based on pca algorithm)

it is useful file for all type of signals

主要用MATLAB实现LMS算法，该算法用途极广，但是核心代码基本上和所上传内容一致。(Main LMS algorithm in MATLAB, the algorithm uses a very wide, but the core code and the upload is basically consistent.)

基于matlab的人脸识别程序 (Face recognition program based on MATLAB)

Matlab中的基本数据类型是向量和矩阵，所以很自然地，信号处理工具箱中的信号也用向量或矩阵表示。列向量和行向量表示单通道信号，矩阵表示多通道信号，矩阵中的每一列表示一个通道。(The basic data types in Matlab is a vector and matrix, so naturally, Signal Processing Toolbox is also used in the signal vector or matrix. Column vector and row vector and single-channel signal, matrix multi-channel signal, a matrix each column represents a channel.)

说明：  这是一篇关于多用户下行链路预编码的文章，主要是从一些基本的矩阵变换以及矩阵运算方面讲解一些原理，最后给出仿真实验
