Abstract

This paper proposes a new phase noise compensation scheme for 60 GHz OFDM system employing optimal blind data detection based on quantum genetic algorithm to alleviate performance degradation due to the phase noise. High data-rate OFDM system in 60-GHz millimeter-wave band have been extensively studied, but the relatively large phase noise in the phase locked loop (PLL) synthesizer severely degrades transmission performance. This proposed scheme employ an optimal (maximum a posteriori) data estimator, utilizing prior statistical knowledge of PHN. In addition, quantum genetic algorithm is used to further reduce the computational complexity. Simulation results under 802.15.3C system show that the proposed scheme mitigates the degradation due to PHN effectively over both AWGN channel and frequency selective fading channel.
