说明：   exp-4: To observe the BER performance a SISO system with Non coherent modulation with Rayleigh fading channels.

使用MATLAB语言实现BP神经网络的分类功能，代码很简洁(using MATLAB BP neural network classification function, a very simple code)

信号处理中短时傅里叶变换（STFT）的实现，可用于实时系统，实时语音处理或者分段的FFT计算，亲测可用，拿走不谢！(The implementation of short time Fourier transform (STFT) in signal processing can be used for real-time system, real-time speech processing or segmented FFT calculation!)

该程序主要提供了信号多径传播的模型，直观看出多径的情况(The program provides a major multi-path signal transmission model, an intuitive multi-path to see the situation)

matlab实现fisher判别，对于统计方面有重要的应用，适合初学者学习(fisher discriminant matlab realize, for statistics has important applications, suitable for beginners to learn)

本程序可绘制无码间串扰的眼图，可设置显示不同的升余弦滚降系数以及眼图个数！希望对大家有用！(This program can be drawn Uncensored crosstalk eye-diagram, you can set different raised cosine roll-off factor and the number of eye diagram! I hope useful for all of us!)

基本的MATLAB界面设置,未说到具体M编程和调试(The basic MATLAB interface settings, not when it comes to specific programming and debugging M)

说明：  何衍庆的matlab教程经典的 具有许多的程序举例 具体应用 源程序等等(Matlab tutorial the classic procedure has many specific applications, for example source code, etc.)

FACS表情图释，包括肌肉图解和各种表情的诠释，有助于人脸表情识别研究学习(FACS expression emoticons, including muscle illustrations and expressive interpretation, contribute to the study of facial expression recognition learning)

自己编写的随机子空间算法，可以用作参考，希望对大家有所帮助(Random subspace algorithms I have written, can be used as a reference)
