【Abstract】 A method of FFT based wavelet transform algorithms was presented by analyzing the properties of not compact supported (or not all compact supported)orthogonal wavelet basis,which does not hurt the transform effect but speed the computing,and help the wavelet transform to be implemented faster. Based on the comparison with other fast algorithms,better speed and effect was obtained. It was used in our project about hydroelectricity data fusion simulation system of FengMan, JinLin, China.更多还原
