CDMA多用户检测中传统检测器，解相关检测器，LMS检测器，以及bp网络多用户检测器的程序(CDMA multi-user detection traditional detector, decorrelation detector, LMS detector, bp network and multi-user detector procedure)

说明：  matlab源代码 C4.5算法 经典算法 这里有具体的操作 是为.M文件 (C4.5 algorithm matlab source code there is the classical algorithm for the specific operation. M files)

利用matlab对暂态信号进行短时能量分析，频谱分析，以及短时傅里叶变换。(Use of matlab for short-term energy of the transient signal analysis, spectrum analysis, and short time Fourier transform.)

基于matlab的自相关序列产生.用到了分数阶高斯噪声和Hurst参数.(Based on the autocorrelation matlab generated sequence. Used a fractional Gaussian noise and Hurst parameter.)

实现CDMA系统的RAKE接收,比较最大比合并、等增益合并、、选择合并接收算法的性能，采用3条多径，每条多径之间延迟半个码片，信源输入采用16位WALSH码扩频(Realize RAKE receiver CDMA system to compare maximal-ratio combining, and so gain the merger, and select to receive the combined algorithm, using more than three tracks, each multi-path delay between the half-chip, input source code using 16 WALSH Spread Spectrum)

说明：  此程序用来进行信道延迟，和序列互相关的。(This procedure used for channel delay, and the sequence of inter-related.)
