精确重建滤波器组的快速设计方法

A Fast Design Method of Filter Banks Satisfying Perfect Reconstruction

介绍了一种线性相位精确重建余弦调制滤波器组的设计方法,并总结了实验结果,提出了一种设计高通道数滤波器组的快速算法。

In this paper,an design method of lin ear -phase cosine -modulated filter banks satisfy-ing perfect reconstruction is intro duced.And we propose a fast algorith m to design filter banks with high channel number from the conclusion o f the experiment result.
