Abstract
In this paper, we propose a novel timing synchronization method for orthogonal frequency division multiplexing (OFDM) systems with a single-symbol preamble. The proposed method has an impulsive timing metric and outperforms the conventional methods in multipath fading channels by averaging M 0 differential correlations of the preamble. Using this method, the system will achieve accurate timing synchronization and keep low out-of-band radiation. Performances of the proposed estimator with different M 0 values are evaluated in terms of bias and mean square error (MSE). Simulation results validate the effectiveness of the proposed timing synchronization method.
