采用时频分布参数来描述语音特征，对基于正弦模型的多种时频参数进行了比较(Time-frequency distribution parameters used to describe the voice characteristics of the multiple sinusoidal model-based time-frequency parameters are compared)

该matlab程序是IEEE 802.11b的物理层仿真程序，仿真了1Mbps下DBPSK调制方式的BER(this is a matlab programme which simulat the ber of IEEE 802.11b with DBPSK in 1Mbps.)

使用Matlab实现的关于主分量分析PCA的方法的案例，可先实现仿真(Matlab achieved using principal component analysis PCA on the case method, the simulation can be achieved)

这两个程序用于仿真 图4和图5.这里的方程用新的归一化方程，不是孤子归一化方程。也就是论文中的方程3(study input peak power vursus output total power for different Lcd, P~P CURVES Simulate Fig.4 Using wangs equations )

很不错的程序，里面有详细的注解说明，可以拿来借鉴一下(very good procedure, there are detailed explanatory comments can be used to learn some lessons from)

基于matlab编写的QQ表情程序，内有说明(QQ expression program based on Matlab prepared)

经典matlab培训课件,非常好,简单易学.(Matlab classical training courseware, very good, easy to learn.)
