频谱方差在语音信号端点检测中的应用，matlab程序，实用。(spectrum of the voice signal variance endpoint detection, the application procedures Matlab and practical.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get some diversity gain.)

gmsk的matlab调制程序，有详细的解释，很好用。(GMSK modulation function)

LPP是局部保局投影方法，这里给出了matlab的源码(lpp code for face recognition)

齿轮啮合刚度曲线,用来计算齿轮啮合动力学作为参考的一个很不错的例子。(It is a similar method,you can change some one from it.)

spread spectrum CDMA application

基于泛化自回归的源模型，以及在这个模型基础上的EM算法实现(Generalization based on the source from the regression model, as well as in the model based on EM algorithm)

说明：  给出正弦加噪函数，通过FFT,DTFT,做频谱变化，幅度谱和相位谱。(Sine plus noise function is given by FFT, DTFT, make changes in the spectrum, amplitude spectrum and phase spectrum.)

说明：  AM调制，利用载波查表，基带信号，C语言实现功能(AM using table for carrier and baseband signals)
