dc.description.abstractIn 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.
