【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更多还原

【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.更多还原
