摘要

本文提出了一种基于子带分解的自适应IIR滤波器，并引入了子带ARMA模型来推导该滤波器。然后提出了子带IIR自适应滤波器。提出的子带IIR滤波器在每个子带采用降阶自适应IIR滤波器，可以近似于高阶自适应ARMA系统。计算机仿真结果表明，该子带IIR滤波器的收敛性能优于传统的并行形式自适应IIR滤波器。

Adaptive IIR filtering employing subband decomposition

In this paper, a novel adaptive IIR filter employing subband decomposition is presented, To derive the subband IIR adaptive filter, the subband ARMA model is introduced. Then the subband IIR adaptive filter is proposed. The proposed subband IIR filter employs reduced order adaptive IIR filter in each subband, which can approximate high order adaptive ARMA system. The computer simulations reveal that the convergence performance of the proposed subband IIR filter outperforms the conventional parallel form adaptive IIR filter.
