小波降噪首先对信号进行小波分解，一般地，噪声信号多包含在具有较高频率的细节中，从而，
可利用门限阀值等形式对所分解的小波系数进行出来，
然后对信号进行小波重构即可达到对
信号降噪的木的。
对信号降噪实质上是一直信号中的无庸部分，
恢复信号中有用部分的过程。
-Wavelet denoising first signal wavelet decomposition, in general, the noise signal contained in a more details of a high frequency, thus, to use other forms of threshold threshold decomposed wavelet coefficients out, and then the signal wavelet weight Structure of the signal noise reduction can be achieved by wood. The signal noise in the signal is essentially beyond been part of the useful part of the signal recovery process.
