【摘要】 推广了双正交小波的概念.引进了多尺度平移伪框架的概念.给出了它的塔式分解格式及其存在的条件.进而得到平方可积函数空间的函数仿射伪框架展式.
【Abstract】 The notion of a generalized multiresolution structure biorthogonal wavelets is introduced,and the concept of affine pseudoframes of L~2(R)is given.The pyramid decomposition scheme of a generalized multiresolution structure is presented,which is similar to Mallat’spyramid algorithm.Anecessary and sufficient condition for the existence of the pyramid decomposition scheme is presented.Moreover,affine frame pseudoframe expansions of L~2(R)are constructed by virtue of the pyramid decomposition scheme.
