摘要
推广了正交小波包的概念.给出一类矩阵值正交小波包的定义及其构造,讨论了矩阵值正交小波包的性质,由矩阵值正交小波包得到了空间L2(R,Cs×s)的一个新的正交基.
The concept of orthogonal wavelet packets was generalized. The definition and the construction of a class of orthogonal matrix-valued wavelet packets was given. The properties of matrix-valued wavelet packets was discussed. A new orthogonal basis of L^2(R,C^s×s) was derived from the orthogonal matrix-valued wavelet packets.
