Abstract :
An efficient timing offset estimation method for orthogonal frequency division multiplexing(OFDM) systems is presented. The performances of the timing offset estimators in multipath fading channel are compared in terms of mean and mean-square error (MSE). The simulation results show that the proposed estimator is unbiased and has significantly smaller MSE.
