主要讲述MATLAB经典、常用的命令，并加以举例说明，可读性强！(tell the detail use of classic and common used MATLAB codes)

基于DTW的语音识别，GUI界面，能识别0-9数字，正确率90 。(Based on DTW speech recognition, the GUI interface, can identify 0-9, 90 accuracy.)

matlab 信号处理（清华大学出版社）一书第10章源代码(Matlab Signal Processing (Tsinghua University Press) Chapter 10 Source Code)

GSM中GMSK调制信号的产生，对信号进行频谱分析及滤波，匹配追踪和正交匹配追踪。( GSM is GMSK modulation signal generation, The signal spectral analysis and filtering, Matching Pursuit and orthogonal matching pursuit.)

This MATLAB code plot the aperture efficiency Vs the subtended angle. The user enter the value of n (2,4,6 or 8) and the code will plot and tell what is angle value that achieves max efficiency and the value of this efficiency.

PLL锁相环的角度生成问题，角度的代入运算前的修正问题，总算是解决了！(PLL PLL angle generation problem, the angle of substitution before the operation to fix the problem, finally solved!)

LS（Least Square，最小二乘法）算法是信道估计算法中最基本的算法之一。在MIMO-OFDM系统中，经常选择LS算法或其改进算法对信道进行估计。利用LS算法设计信道估计器，算法结构简单易于实现，且估计器不需要知道信道中各个收发天线对之间的自相关矩阵和噪声。(LS (further Square, Least Square) algorithm is one of the most basic algorithm of channel estimation algorithm. In MIMO- OFDM systems, often choose LS algorithm and its improved algorithm for channel estimation. Use of channel estimator and the LS algorithm design algorithm structure simple and easy to implement, and the estimator does not need to know in the channel between the sending and receiving antenna for autocorrelation matrix and noise. )

图像重采样程序，可以实现图像任意大小的尺寸调整，采用分片重采样方法(Image resampling process, image of any size can be adjusted, subdivision resampling methods )

运用matlab实现数字滤波器，主要是采用的频率采样法(Realize the use of matlab digital filter is mainly used in the frequency sampling method)
