摘要
通过引进双向向量值多分辨分析与多带多重双向向量值小波包的概念.运用矩阵理论和时频分析方法,刻画了多带多重双向向量值小波包的性质,得到多带多重双向向量值小波包的正交公式,并且也得到了向量值函数空间L^2(R,R^3)的正交基.
The notion for vector-valued two-direction multiresolution analysis and multiple vector-valued two-direction m- band wavelet packets are introduced. The properties for multiple vector-valued two-direction m-band wavelet packets are char- acterized by virtue of matrix theory and time-frequency analysis method. The orthogonal relationship formulae concerning the multiple vector-valued two-direction m-band wavelet packets are obtained. Moreover, orthogonal bases of L2 （R ,R3） are con- structed.
