摘要

利用导频辅助策略研究正交频分复用(OFDM)系统时变信道估计问题。提出了一种不依赖于信道统计量的鲁棒估计方法。推导基于约束滤波方法，并分析了特殊情况。仿真结果表明，与文献中报道的估计器相比，该建议具有更好的性能。

Robust pilot-aided channel estimator for time-varying OFDM channels

This paper deals with time-varying channel estimation in orthogonal frequency division multiplexing (OFDM) systems by means of pilot-aided strategies. A robust estimator which does not depend on the channel statistics is proposed. The derivation is based on a constrained filtering approach and particular cases are analyzed. Simulation results are provided in order to verify the better performance of the proposal when compared to estimators reported in the literature.
