Novel ICI suppressing receiver for high-mobility DVB-T2 reception with large FFT modes
Paper in proceedings, 2011

This paper proposes a novel framework for reducing the inter-carrier interference (ICI) caused by time-varying channels in mobile OFDM systems. The proposed ICI suppressing scheme is based on the application of the sum-product (SP) algorithm to a factor graph (FG) representing the joint a posteriori probability (APP) of the transmitted symbols. Simulation results show that this new iterative soft-input soft-output (SISO) detection strategy achieves good performance when the ICI power is high, which can be due to high mobility or the use of large FFT sizes. We discuss its application to the reception of the new DVB-T2 broadcasting standard for a set of realistic mobile scenarios.
