滑动窗快速横向滤波的自适应判决反馈均衡器算法

本文提出了一种基于滑动窗广义多路快速横向滤波（ＳＷＦＴＦ）的自适应判决反馈均衡器（ＤＦＦ）算法，它具有快速跟踪性能，故可用于快速时变多径衰落的信道。文中推导了ＳＷＦＴＦ－ＤＦＥ算法。在数字移动通信信道模型上，利用计算机模拟，在均方误差和误码率特性方面与其它均衡器算法进行了比较。

A Sliding Window Fast Transversal Filter Adaptive Decision Feedback Equalizer Algorithm

This paper proposes a novel decision feedback equalizer(DFE)algorithm based on a sliding window generalized multichannel fast transversal filter(SWFTF).The SWFTF DFE algorithm has fast tracking property,therefore it can be employed in rapidly time-varying multipath fading channels.In this paper,the derivation of the SWFTF DFE algorithm is presented.On a digital mobile radio channel model,using computer simulation,we compare the SWFTF DFE algorithm with other equalizer algorithms in the characteristics of mean squared error and bit error rate.
