A New Pilot-Aided Integer Frequency Offset Estimation Method for Digital Video Broadcasting (DVB) Systems

In this paper, a new integer frequency offset estimation method is proposed for orthogonal frequency division multiplexing (OFDM)-based digital video broadcasting (DVB) systems. Several pilot-aided frequency offset estimation methods have been proposed for OFDM-based DVB systems. In the conventional methods, however, the information of some combinations that pilots provide is used only. Thus, in this paper, we propose a new integer frequency offset estimation method exploiting the information of all combinations that pilots provide. The simulation results show that the proposed method outperforms the conventional method in terms of the probability of integer frequency offset estimation failure.
