dc.description.abstract | In orthogonal frequency-division multiplexing
(OFDM)-based wireless local area networks (WLANs), phase noise (PHN) and channel estimation errors can degrade the performance of the system. This letter provides a soft decision decoding scheme analysis for OFDM-based WLANs in the presence of PHN and channel estimation errors. Basing on this analysis, we propose a novel iterative scheme for joint channel estimation with PHN suppression and soft decision decoding. In addition, the soft decision decoding metric for QAM OFDM systems is modified to mitigate the effects of PHN and channel estimation errors. The simulation results show that the proposed scheme mitigates the performance degradation due to PHN and channel estimation errors effectively. | en |
