dc.description.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.	pt_BR
