小波变换是克服其他信号处理技术缺陷的一种分析信号的方法。小波由一族小波基函数

构成，它可以描述信号时间（空间）和频率（尺度）域的局部特性。采用小波分析最大优点

是可对信号进行实施局部分析，可在任意的时间或空间域中分析信号。

-Wavelet transform is a signal processing techniques to overcome the other deficiencies of a signal analysis method. By the family of wavelet basis function of wavelet

Composition, it can describe the signal time (space) and frequency (scale) domain of the local characteristics. Biggest advantage of using wavelet analysis

Is a partial analysis of the signal, at any time or spatial domain analysis of signals.
