A new level set model without initialization, very time efficient compared with former level set model.(A new level set model without initializati on, very time efficient compared with former level set model.)

本程序的性能已经达到较高水平，采用波束成形技术的BER计算，有详细的注释，可以得到很精确的幅值、频率、相位估计。( The performance of the program has reached a high level, By applying the beam forming technology of BER There are detailed notes, You can get a very accurate amplitude, frequency, phase estimation.)

MSK modulation and demodulation with carrier recovery

MMSE解相关多用户检测器和CD传统多用户检测器的误码率比较（八个用户）程序( MMSE decorrelating multiuser detector and CD traditional multi-user detector error rate (eight users) procedure)

好的简单的源码程序　很好用的　基于ＭＡＴＬＡＢ　编写　无密码，下载解压即可(Good simple procedure useful source MATLAB-based preparation of non-password, download decompression can)

说明：  MATLAB7.X数字信号处理基础教程及源程序和课件。(MATLAB7.X digital signal processing based on source code and tutorials and courseware.)

无循环实现S变换，S变换在信号分析中十分有效，它的时空分辨率要高于小波变换，效率很高的程序(This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here: djj.ee.ntu.edu.tw/S_Transform.pdf‎ )

matalb实现的协同过滤，里面包含很多重要算法，都已经实现(matalb achieve collaborative filtering, which contains many important algorithms have been realized)

说明：  信号预处理，提取PCG特征，利用机器学习进行分类（含数据）(Signal preprocessing, PCG feature extraction, machine learning for classification (including data))
