这是对一维信号进行五层小波分解，然后分别把不同层数的细节分量和近似分量重组这个信号。这样有除噪和最大程度提取信号能量的效果。-This is a five-story one-dimensional wavelet decomposition of signals, and then the details of each component of different layers and approximate quantity of restructuring the signal. In addition to such a degree of noise and maximum signal energy extraction results.
