摘要

本文提出了一种新型结构的自适应滤波器

称为组合时延自适应滤波器。这种新的结构与传统的查表结构自适应滤波器相比

具有复盖较长时延的信号响应和收敛速度快的特点。这种滤波器适用于ISDN U—接口全双工传输系统中作为自适应回波消除器。本文讨论了这种滤波器的算法

特性及应用

并给出了一组实验结果。

Abstract

A new adaptive filter

called the combined time-delay adaptive filter

is proposed in this paper. Compared with the traditional lookup table adaptive filter

the new configuration can synthesize a signal response with a long time delay and has the characteristic of fast convergence speed. The new adaptive filter can be used as an echo canceller in ISDN U-interface full-duplex transmission system. The paper discusses the algorithm

characteristics and application of the filter. A set of experimental results are given.
