摘要

本文对话音频带数据回波抵消器的实现方法提出了一个重要的改进

使得话带数据回波抵消器所需的运算量和系数存储量大幅度减少

这在回波路径较长或需要考虑远端回波的情况下尤为突出。

Abstract

In this paper

an essential improvement has been proposed for implementation of voiceband echo cancellation. The new configuration requires much less computations than that of the existing configurations

especially for the cases where the impulse response of the echo path is long or the far-end echo has to be considered.
