摘要

针对短波电台入网中对回波抵消的要求，本文提出采用基于ＬＳ准则的ＦＴＦ算法，同时把“稳健估计（ＲＥ）”应用于ＦＴＦ算法中，并设计出一种新的自适应回波抵消器结构．理论分析和计算机模拟结果都表明该回波抵消器具有收敛速度快，稳态误差小，稳定可靠，抗干扰能力强等特点，明显地提高了短波电台入网的性能．

Abstract

According to the requirements of echo cancellation in the short wave access network

this paper adopts LS based FTF algorithms

applies the estimation method to it and proposes a new architecture of adaptive echo cancellation.The theorectical analysis and simulation results show that the adaptive echo cancellation has fast convergence

small steady state error and robust performances.
