| Abstract: | 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. |
