读取wavepro7100的2进制文件头参数 返回4个参数：采样长度，增益，偏移量，时间间隔 ylj 2005.6.9(2 M wavepro7100 read file header parameters The return of four parameters: the sampling length, gain, offset, time interval)

mean square error calculation

非常好而且比较经典的批处理最小二乘参数估计算法。(Very good and classic batch least squares parameter estimation algorithm.)

kernel PCA feature extraction

线形调频信号带码调制,程序是自己写的 仿真效果也不错 环境是MATLAB(Linear FM signal with modulation code, the program is to write their own simulation results would be a good environment is a MATLAB)

matlab 高阶谱工具箱，包含了信号分析的bispecd,bispeci,bispecx,bicoher等30多个函数(order spectrum matlab toolbox contains a signal analysis bispecd, bispeci, bispecx, bicoher, more than 30 functions)

基于 MATLAB 的语音信号分析与处理的课程设计.录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法或双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的语音信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号(MATLAB-based voice signal analysis and processing of the curriculum. Record a voice signal itself, and the recorded signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum filter performance given by using window method or the bilinear transformation to design a filter, and draw the filter frequency response then filter of their own design collection of the speech signal is filtered, the filtered signal to draw the time domain waveform and frequency spectrum, and filter the signal before and after comparison, analysis of signal changes playback voice signal)
