Abstract

In this paper, we propose a novel timing synchronization method for orthogonal frequency division multiplexing (OFDM) systems with a singlesymbol preamble. The proposed method has an impulsive timing metric and outperforms the conventional methods in multipath fading channels by averaging 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 values are evaluated in terms of bias and mean square error (MSE). Simulation results validate the effectiveness of the proposed timing synchronization method.
