ECHO

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

关于维纳滤波器,维纳滤波程序，有注释，比较实用(Wiener filtering process, more practical)

利用旋转不变方法对信号的波达方向进行估计，主要用于窄带信号(DOA estimation by ESPRIT)

采用MATLAB编制的Kalman滤波程序，比较全面，还可以一看。(Kalman filtering using MATLAB compiled procedures, more comprehensive, you can have a look.)

国外求延时、嵌入维数、模糊、混沌等非常好用的工具包。(OpenTSTOOL)

回声信道模型,双通道,无法正确识别的情况.(Echo channel model, dual-channel, can not correctly identify the situation.)
