The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.

基于matlab的二维图像PCA特征提取(PCA feature extraction from image by matlab)

说明：  扩频系统中的小实验，具体介绍在文件kuopin_all中有介绍。(spread spectrum system of small experiments, which are detailed in the document kuopin_all were introduced.)

Some methods Applied in matlab

对灰度图像采用Arnold混沌加密，实现图像置乱加密(By Arnold on the gray image encryption, encryption of image scrambling)

将matlab图形嵌入到C#窗口，源文件有注释(Matlab graphics will be embedded into C# Window, the source file has the Notes)

说明：  Leader Selection for optimization algorithms

说明：  此程序是用于模式分类的在matlabhu环境下的原代码，AI该程序是在三层bp网络的基础上结合小波知识实现的(This procedure is used for pattern classification matlabhu environment in the original code, AI that the procedure was in bp in the three-tier network based on the combined knowledge of the realization of the wavelet)

该matlab函数用来计算理想无耗传输线上电压电流的分布，用户需要给定传输线的特性阻抗、电长度以及出事端的反射系数。(Matlab function used to calculate the ideal power transmission lines without the distribution of voltage and current, users need to set the characteristic impedance of transmission lines, electricity, as well as the length of the reflection coefficient of trouble.)
