Abstract
The frequency offset estimation for OFDM systems using the correlations of several identical parts in the preamble is addressed. We design a novel preamble which is composed of one irregular OFDM training symbol block with odd numbers of identical parts and one regular OFDM training symbol block with even numbers of identical parts. Based on the designed preamble, we propose a novel frequency offset estimator. Simulation results show that the proposed frequency offset estimator has the larger estimate range advantage over the conventional estimator while maintaining approximately the same performance
