正交频分复用系统时域均衡器的一种优化准则
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.
