BPSK

语音分帧程序，对一个语音信号进行分帧，并研究分帧后的短时能量和过零率特性(Voice framing procedures, a voice signal framing, and to study the sub-frame after the short-term energy and zero crossing rate characteristics)

基于PCA的人脸识别代码，识别率可达88 (PCA-based face recognition code, the recognition rate up to 88 )

先进PID控制及Matlab仿真（第二版）PID，(advanced PID control and Matlab (2nd Edition) PID,)

先进PID控制方法的matlab仿真刘金坤编著有编好的程序很有用 (Advanced PID control method for a matlab simulation program has made very good use)

讲述经验模态分解的应用，对于其原理及消噪功能有很好的介绍(About the application of EMD)

在程序中用一般的MUSIC方法估计了信号的频谱，从两图中可看出在信号各频率处，频谱的峰值较大，故能明显的与噪声相区别，可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。(MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum peak larger, and it could be significantly distinguished from noise in the signal can be avoided to some extent a lesser extent, the signal is noise submerged.)

matlab code for peak of speach

ldcp编码解码源程序，用c语言写的，最后生成mex文件用于matlab使用 (ldcp codec source code, using c language, and finally generate mex file for matlab use)

matlab编码程序 主成分分析 有实例 直接应用即可(Matlab coding program principal component analysis is directly applied to an example.)

说明：  Hausdorffn距离的Matlab程序(Matlab Program for Hausdorffn Distance)
