摘要
本文给出一种任意伸缩矩阵正交小波包构造方法 .该小波包是以频域形式给出的 ,文献 [1 ]所给小波包仅是其一特例 .这样所得的小波包使得 L2 (Rs) 中小波基的选择更灵活 。
In this paper, we give an algorithm for constructing orthogonal wavelet packets of arbitrary integer valued dilation matrix. These wavelet packets are given in frequence domain, and the wavelet packets given in [1] are just special examples of it. Therefore we can draw bases for L 2(R s) from this wavelet packets flexibly. Finally, an example is given to demonstrate this method.
