小波去噪matlab程序,在噪声环境下语音信号的增强,语音信号为读入的声音文件,噪声为正态随机噪声,在小波基 db3 下进行一维离散小波反变换.-Matlab wavelet denoising procedure, noise enhancement of speech signals, speech signal is read into the sound file, the noise is normal random noise, the wavelet ' db3' u

能将频带分解为几个不同频率的信号，可以帮助程序员在做小波变换时使用-Band decomposition can be for several different frequency signal，Can help programmers to use when doing wavelet transform

本案例通过对图像加入高斯噪声，利用sym4小波函数对该图像和信号进行三级分解，用小波阀值去噪的方法对该图像进行去噪，并给出了仿真结果。-This case through join Gaussian noise image, use the sym4 wavelet decomposition of the image and signal, the wavelet threshold to filter method for the image denoising is presented,

MATLAB实现声音信号的小波分解与重构内副数据 不错的-MATLAB voice signal wavelet decomposition and reconstruction of the pair of data is good
