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

对信号波形进行小波变换并分解，提取模极大值，最后进行信号重构。(Wavelet transform and decompose the signal waveform, extract the maximum value of the modulus, and finally reconstruct the signal.)
