In this paper, we address the challenging problem of the OFDM reception in the presence of phase distortions. Phase noise and carrier frequency offset seri ously degrade the performances of OFDM systems by destroying orthogonality of the subcarriers. Ba ed on a Markov Chain Monte Carlo sampling mechanization, our approach consists in jointly estimatin g he phase noise, the frequency offset and the transmitted symbols. The proposed algorithm is implemente d in the time domain in order to benefit… CONTINUE READING
