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 semiorthogonal wavelet packets of L2(Rs) 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 L2(Rs) flexibly.
