说明：  解相关多用户检测的MATLAB程序，多用户检测的入门学习(Decorrelating multi-user detection of MATLAB procedures, multi-user detection entry Learning)

说明：  DSP本身在内的所有电子器件都是干扰源，而且系统所处的工作环境中还有很多外来干扰源，再加上语音识别技术对信号噪声非常敏感，所以在系统设计中必须考虑系统的抗干扰问题。(DSP itself, including all electronic devices are sources of interference, and the system environment in which there are many external sources of interference, coupled with voice recognition technology is very sensitive to signal noise, so the system design must consider the system of anti- interference problem.)

追赶法求解，可以直接调用，抛物方程紧差分(Chasing method can be called directly)

说明：  里面有不少MATLAB学习课件,对新手很有帮助。(there are many study matiarial)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)
