利用DGHM多小波滤波器构造α带多小波
Construction of α-band multi-wavelet by using DGHM multi-wavelet filter
摘要
Abstract
Using DGHM multi-wavelet filter, this paper obtained a new matrix (-CQF) by a method that increase its length towith supplementing the zero-matrix. A novel transformation of matrix filter was introduced. In comparison with the traditional methods, the order of some polynomial ma-trices need not be decreased row by row and the polyphase matrix need not be factorized into a special form. Furthermore, this method was not restricted by the length of the filter. Therefore, an algorithm was presented in this paper for constructing-band orthogonal multiwavelets from the as-sociated multi-scaling function.关键词
