摘要:
研究了高维向量值小波包的构造与性质,引进了数量矩阵伸缩的高维向量值小波包的概念.运用有限群理论和算子理论与积分变换,讨论了它们的性质,得到了高维向量值小波包的正交公式.利用高维向量值小波包的正交性,构造了空间L2(Rs,Cr)的新的正交基.

Abstract:
The construction and properties of vector-valued multivariate wavelet packets are studied. The notion of vector-valued multivariate wavelet packet associated with a quantity matrix is introduced. Their properties are discussed and orthogonality formula concerning these wavelet packets are obtained by means of finite group theory, operator theory and integral transformation. Finally, some new orthogonal bases for L2(Rs,Cr) are constructed from an orthogonal multivariate vector-valued wavelet packets by virtue of their orthogonality.
