Decision-directed phase noise compensation for millimeter-wave single carrier transmission systems with frequency-domain equalization

This paper proposes a receiver that performs frequency-domain equalization (FDE) and decision-directed phase noise compensation (DD-PNC) and that can cope with multipath delay and phase noise for a millimeter-wave single-carrier (SC) transmission system. In an initial process of the proposed receiver, a cyclic prefix (CP)-based phase noise compensator (CP-PNC) removes the phase noise by using CP, which is known to the receiver, and the channel is equalized by FDE. In an iterative process, DD-PNC estimates the phase noise at each sampling time by using outputs of a decoder and compensates time-domain received signals for the phase noise by using the estimates. Computer simulations following the 60-GHz wireless PAN standard demonstrate that the proposed receiver with the three iterations can achieve excellent transmission performance, when 64QAM with the coding rate of 3/4 is employed and the phase noise level is -85 dBc/Hz at 1 MHz offset.
