| Abstract: | In this paper , we adopt the method of poly phase decomposition of frame operator to construct a new class of equivalent filter banks depending on the theory of M-band wavelet transform and filter banks. By means of this method in this paper , it is convenient to com pute wavelet coefficient of any level if we know the original data and equivalent filter bands, which provides the possibility for real-time disposal. |
| Keywords: | frame operator possibility poly phase decomposition filter banks wavelet coefficient |
