摘要
本文给出d带双正交小波子带算子的定义,通过发展d-循环矩阵理论,得到子带算子的界就是循环矩阵谱半径的极限以及子带算子的界估计,并且通过实例来验证得到的结论.
A concept of sub-band operator is introduced, a d-circular matrix method is developed and the exact bounds of the sub-band operators are obtained. An example is provided to illustrate the proposed results in this paper.
