Abstract

Orthogonal frequency-division multiplexing (OFDM) has been specified by IEEE 802.11a standard as the transmission technique for high-rate wireless local area networks (WLANs). Performance of an OFDM system, however, is heavily degraded by random Wiener phase noise, which causes both common phase error (CPE) and inter-carrier interference (ICI). To mitigate this problem, a new phase-noise suppression (PNS) algorithm is proposed in this letter to efficiently eliminate the effect of phase noise on OFDM based WLANs. Numerical results are presented to illustrate the effectiveness of the proposed algorithm.
