一个有用的声学回声消除器的设计源码，还不错哦～(A useful acoustic echo cancellation design source, oh well ~)

图像压缩 对现有的二维图像利用二维小波进行图像压缩(Image compression)

最大类间方差法求阈值(thanks)

对光纤系统中的NRZ时域和频域特性进行了描述，值得一看(fiber NRZ system of time-domain and frequency domain characteristics of the description of an eye-catcher)

对某一标准图像进行二维Mallat小波的3级分解，获得小波高/低频系数，分别 用低频分量LL1、LL2、LL3的小波系数进行图像重建，分别计算这三种情况 和原始图像比较的PSNR。(A standard image 3 2D Mallat wavelet decomposition, wavelet high/low frequency coefficients , respectively Low frequency component LL1 , LL2, LL3 wavelet coefficients for image reconstruction, respectively, to calculate the three And compared to the original image PSNR. )
