离散理想滤波器组合系统及其应用(英文)

Discrete Ideal Filter Bank and Its Application

作者考察变换域滤波器组合系统之一 ,离散理想滤波器组合及其在信号处理中的应用。变换域滤波器组合是子带分割及小波分解与合成的新发展。迭代匹配理想滤波器组合 (IM IFB)结构简单 ,应用方便 ,有快速算法 ,可实现理想频带分割 。

In this paper, a kind of transform filter bank based on discrete orthogonal transform, discrete ideal filter bank and its iterated system and the application to signal analysis and processing will be discussed. The transform filter bank is the development of sub band splitting and wavelet decomposition and composition. The iterated matched ideal filter bank has very simple structure and fast algorithm. It can be applied to many aspects of signal processing.
