摘要 给出紧支撑多元半正交小波包的构造算法。该小波包的特点是:分解系数的选取具有多样性,并且该小波包是基本小波包推广的广义小波包。利用该小波包可使L2(Rs)中小波基的选择更灵活。 An algorithm to construct compactly supported semiorthogonal wavelet packets of L2(Rs) is presented. We have a wide choice of the decomposition coefficients in our construction, furthermore the wavelet packets are generalization of the basic wavelet packets. With these packets. We can choose the various bases of L2(Rs) flexibly.
