Matlab符号数学工具箱，数理统计工具箱，神经网络工具箱，微分方程工具箱应用简介(Matlab Symbolic Math Toolbox, mathematical statistics toolbox, neural network toolbox, toolbox application of differential equations Introduction)

Blind Source Seperation (BSS) now is a important technology. Independent Component Analysis (ICA) is the main technique of BSS. Suppose we mix many non-Gausse signal sources,ICA can seperate the mixed signal to orignal signals without any information. This Matlab Code simulate the using ICA for Multi User Detection (MUD) in CDMA system. We demo the CDMA system with 30 Users, and use ICA seperate the signal of each user at Base Transmit Station (BTS) with the only 30 Users signal.

隐马尔科夫模型是语音识别中的重要算法思想，这里在matlab下实现了一个原理性的算法(Hidden markov models is an important algorithm in speech recognition, here under the matlab implements a rational algorithm)

模式识别中的bayes判别分析算法，有PMUSIC 校正前和校正后的比较，实现了图像的加水印，去噪，加噪声等功能。( Pattern Recognition bayes discriminant analysis algorithm, A relatively before correction and after correction PMUSIC, Realize image watermarking, de-noising, plus noise and other functions.)

This program uses the waterfilling to compute capacity

说明：  PLL是一个锁相环模块，能得到波形的相角，从而实现同步信号的控制(PLL is a phase-locked loop module, waveform, phase angle, in order to achieve the control of the synchronization signal)
