In this letter, a phase noise reduction algorithm for orthogonal frequency division multiplexing (OFDM) systems with an input of higher-order constellation is proposed to achieve high data rate transmission. The proposed algorithm estimates dominant interchannel interference (ICI) terms, caused by phase noise, using the subcarriers adjacent to pilot subcarriers, and compensates the OFDM signal using these estimates. Also, the length of dominant ICI terms is efficiently determined by estimating 3 dB bandwidth of phase noise. The proposed algorithm is shown to reduce the effect of phase noise on OFDM systems with an input of higher-order modulation and a large amount of phase noise.
