该程序实现改进的自适应相关算法，两个matlab文件，一个为函数，该函数求出信号特征量的马氏距离平方并通过梯度下降法训练出其固定阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号特征量的马氏距离平方及其固定阈值求出来，并一起画出图来。 (The program features improved adaptive correlation algorithm, two matlab files, one for the function that calculate the square of the Mahalanobis distance of signal characteristics by gradient descent to train the fixed threshold, the other main function, call The function files the program seek out the square of the Mahalanobis distance and fixed threshold of each channel signal, there are four chanel signal,then draw them out together)

用于描述26个英文字母在奇异值分解后的空间平面的分布(the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the )

视频处理中让视频的前景和背景分离的matlab程序(Video processing--to realize the separation of foreground and background in a given video sequence )

此m文件为脚本文件，在命令窗口输入命令：midamble，即可执行！ 单元数组--user_m，存储了K个用户的midamble码，user_m{1}对应用户1，以此类推。(This m file for the script file, enter the command in the command window: midamble, which can be executed! Cell array- user_m, stored K users of the midamble code, user_m (1) corresponds to user 1, and so on.)
