In this paper, a novel consecutive-pilot design is proposed to suppress phase noise (PHN) in orthogonal frequency-division multiplexing (OFDM) system. The estimation of PHN is performed by a cross-correlation between the received and locally generated pilots in frequency-domain. Simulations show that the proposed scheme can effectively ameliorate the impairment due to PHN, at the cost of acceptable additional transmission bandwidth and low implementation complexity.
