摘要
In this paper, the notion of orthogonal vector-valued wavelet packets of the space L-2(R-s, C-d) is introduced. A method for constructing the orthogonal vector-valued wavelet packets is presented. Their properties are investigated by virtue of time-frequency analysis method, matrix theory and finite group theory, and three orthogonality formulas with respect to the wavelet packets are established. Orthogonal decomposition relation formulas of L-2(R-s, C-d) are obtained by constructing a series of subspaces of vector-valued wavelet packets. In particular, it is shown how to construct various orthonormal bases of L-2(R-s, C-d) from these wavelet packets. (C) 2007 Elsevier Ltd. All rights reserved.
