摘要

:本文提出了一种新的正交频分复用（OFDM）系统时域均衡器的优化准则

即最小缩短信道方差（MSCSE）准则

基于该准则导出了一种非常实用的优化算法.同时

本文还证明在一定条件下

通常的最小均方误差（MMSE）准则将转化为MSCSE准则

并对各种算法的性能做了比较

Abstract

This paper proposes a new minimum shortening channel square error （MSCSE） criterion for optimizing the time domain equalizer in orthogonal frequency division multiplexing （OFDM） systems.From the new criterion

a very practical algorithm is derived.The paper also proves that the conventional MMSE criterion will be converted into MSCSE criterion on certain conditions.The performance comparisons between different algorithms are carried out.
