杂波模型为重尾噪声，滤波器为kalman-levy滤波器，此滤波器在噪声不是高斯噪声时效果优于卡尔曼滤波器(Clutter model for heavy-tailed noise filter for the the the kalman-levy filter, this filter is better than the Kalman filter noise is not Gaussian noise)

nmap最新windows环境下的源代码，对提高大家的编程能力有很大帮助(The latest source nmap windows environment, to improve our programming skills are very helpful)

GeoPhysics at the University of Alberta 提供的一个基于Matlab的地震处理软件(GeoPhysics at the University of Alberta provided a Matlab-based seismic processing software)

自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。(Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, with the multiplication time was needed. In order to avoid the multiplication using the short time average magnitude difference function (AMDF), verify the AMDF and autocorrelation have a similar effect, that the average magnitude difference function can replace the voice of the autocorrelation function.)
