matlab的书籍，很不错的，包括matlab命令集，很有用的东西。(matlab books, very good, including the matlab command set, very useful things.)

说明：  基于小波包的带通滤波器设计程序。给出了小波变换的快速算法和重构算法，讨论了应用小波变换进行信号带通滤波的方法，并通过正交小波包对信号的分解，把频率成分复杂的信号分解到各个频带上，根据需要提取指定频率的信号，然后用小波包重构算法对信号进行重构，实现对信号的提取。(Based on wavelet packet band-pass filter design program. Given the fast algorithm of wavelet transform and reconstruction algorithms are discussed using wavelet transform signal band-pass filtering method, and through the wavelet packet to signals can be decomposed, 把 frequency components of complex signal is decomposed into various frequency bands 上, according to need to extract the specified frequency signal, and then reconstructs the signal reconstruction algorithm to achieve the extraction of the signal.)

几种窗函数的时域图比较，可以显示图像，直接运行即可(Time-domain diagram of several window functions, can display images, can be run directly )

Script for computing BER with Binary Convolutional Code and Viterbi decoding with finite survivor state memory and variable traceback depth Convolutional code of Rate-1/2, Generator polynomial - [7,5] octal Hard decision decoding is used.

获取图像上的曲线数据，读入一幅图片并选取所需的数据点加以保存处理。用法：使用鼠标左键取点，右键结束取点并保存数据(Get the curve on the image data, read and select a picture to save the data points needed to deal with. Usage: Use the left mouse button to take point, right end of the access point and save the data)

matlab使用说明，希望对初学者有用。(matlab instructions for use, I hope useful for beginners.)

二次指数平滑法，仅供参考。需要学习的可以下来看一看(Secondary exponential smoothing method, are for reference only. Need to learn can be down to take a look at the)

开关磁阻电机，直接瞬时转矩控制，速度闭环，三相6/4 SRM Simulink仿真，可用(Switched reluctance motor, direct torque control, closed loop speed, three-phase 6/4 SRM Simulink simulation, available)

说明：  MIMO谱扩展信道模型仿真，希望对大家有所帮助(MIMO channel model simulation, we hope to help)
