摘要
本文给出了对应于任意整数矩阵伸缩的高维向量值正交小波包的定义及其构造方法．并讨论了这种向量值正交小波包的性质,得到向量值函数空间L2(Rs,Cr)的新的正交小波基．
in this paper, we introduce the notion of orthogonal vector-valued wavelet packets in higher dimensions associated with a given integer-valued dilation matrix. A procedure for constructing the orthogonal multivariate vector-valued wavelet packets is presented. The properties of the multivariate vector-valued wavelet packets have been discussed. Moreover, several new orthogonal bases of L^2（R^#,C^r） are constructed by using the orthogonal vector-valued wavelet packets.
