dc.description.abstractThe joint channel estimation and phase noise
suppression scheme for orthogonal frequency-division
multiplexing (OFDM) systems is proposed for a case where
channel estimation is needed symbol by symbol. In the proposed
scheme, channel estimation and phase noise suppression are
performed iteratively via the expectation-maximization (EM)
algorithm. The proposed algorithm mitigates the performance
degradation due to phase noise effectively while providing the
accurate channel estimate with comparatively few pilot
subcarriers so that the spectral efficiency of an OFDM system is
improved.
