Abstract

In this paper we introduce a novel demodulation scheme for OFDM that jointly handles the effects of strong phase noise (both at the transmitter and receiver) and multipath channel. The basic principle is to model the effects of the phase noise and multipath channel as an FIR filter in the frequency domain with frequency varying taps. The proposed demodulation scheme iterates between the filter estimation based on tentative decision on the transmitted symbols and symbols estimation with a frequency domain Reduced State Sequence Equalizer (RSSE) based on tentatively estimated filter. Simulation results show excellent performance of the proposed scheme compared to previously proposed techniques.
