摘要：
In this article, the notion of a kind of multivariate vector-valued wavelet packets with composite dilation matrix is introduced. A new method for designing a kind of biorthogonal vector-valued wavelet packets in higher dimensions is developed and their biorthogonality property is investigated by virtue of matrix theory, time-frequency analysis method, and operator theory. Two biorthogonality formulas concerning these wavelet packets are presented. Moreover, it is shown how to gain new Riesz bases of space L-2(R-u,C-v) by constructing a series of subspace of wavelet packets.
