Influence and Suppression of Phase Noise in Multi-Antenna OFDM

Overview The influence of phase noise (PN) on the performance of a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based communication system is analyzed. As part of this analysis, an estimator for the common phase error (CPE) is derived, based on the maximum likelihood estimation (MLE), which was chosen for its asymptotic optimality. Since the computational complexity of the MLE procedure clearly rules out a cost effective solution, a reduced-complexity algorithm, based on least squares estimation (LSE) is designed which yields suboptimal performance.
