双正交小波滤波器族的构造
On the construction of bi-orthogonal wavelet filter banks
【摘要】 给出了一般双正交小波滤波器所对应多相矩阵分解形式及所对应的代数结构空间,完成了一个双正交小波滤波器设计程序.此程序不但可以给出任意双正交小波滤波器族参数表示,还可以用来刻划滤波器族代数结构.
【Abstract】 In this paper,the algebraic structure and parametrization factorization of compactly supported biorthogonal wavelet filter banks are well studied.And a program for constructing biorthogonal wavelets has been given.For this program,we can construct any compactly supported biorthogonal wavelets.And the algebraic structure of this filter bank can be shown by the program.
