随机信号的功率谱估计,包括间接法，直接法，weltch法等(Random signal power spectrum estimation)

基于matlab 的MP3音频播放器。能够实现播放、暂停、停止等基本功能。同时可以绘制波形图。(Matlab-based MP3 audio player. Enables play, pause, stop, and other basic functions. At the same time you can draw waveforms.)

matlab开发环境下的谱减法算法，主要用在了作者的语音增强算法当中(development environment under matlab spectral subtraction algorithm, mainly used in the author)

独立主成分分析与主成分分析代码，速度比较快，而且比较好用(In these first experiments, both ICA and whitened PCA are used to compress the data, and all the components are used for classifying the examples. The classifier used is a 1-NN with Euclidean distance. The results shown in next sections are clear: when a rotational invariant classifier is used (as 1-NN with L2-norm) the classification results of FastICA/whitened PCA are equivalent, while the difference between Infomax and whitened data es significant but small)
