Abstract
Wavelet analysis is the inheritance and development of the Fourier transform Firstly,the paper introduces the practical background of wavelet theoky and the basic principles of the wavelet transform,especially the multi-scale analysis theory,Finally,through the experiment,a fractional signal multiscale wavelet transform is realized.
