小波工程主要包括一两部分:一、连续小波分析的应用,二、离散小波分析的应用。下面分两个部分分别说明这两个程序的分析结果:
一、连续小波分析:
所用信号为自己构造的三角波和正弦波叠加的信号:s=(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3+1*cos(n/2)*10。其中第一项(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2为一周期为100的锯齿波,第二项-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3为一周期为34的锯波,第三项为一周期为4*pi正(余)弦波。另外叠加了一幅度为5的噪音信号。
程序包包含程序与说明文档。(Wavelet works mainly consists of two parts: first, the application of continuous wavelet analysis, II, Discrete Wavelet Analysis.)

这是目前传统单通道语音增强中效果最好的算法,作者Iseal Cohen大神,采用基于最小均方误差MMSE准则,代码里,噪声估计由最初的MCRA更新为效果更好的IMCRA。(This is the most effective algorithm for traditional single channel speech enhancement. The author, Iseal Cohen great God, uses the minimum mean square error MMSE criterion. In the code, the noise estimation is updated from the original MCRA to the better IMCRA.)
