IEEE 802.11a 标准已将正交频分复用 (OFDM) 指定为高速率无线局域网 (WLAN) 的传输技术。然而，随机维纳相位噪声会严重降低 OFDM 系统的性能，从而导致公共相位误差 (CPE) 和载波间干扰 (ICI)。为了缓解这个问题，提出了一种新的相位噪声抑制（PNS）算法，以有效消除相位噪声对基于 OFDM 的 WLAN 的影响。数值结果说明了该算法的有效性。
Orthogonal frequency-division multiplexing (OFDM) has been specified by the IEEE 802.11a standard as the transmission technique for high-rate wireless local area networks (WLANs). The 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 to efficiently eliminate the effect of phase noise on OFDM-based WLANs. Numerical results are presented to illustrate the effectiveness of the proposed algorithm.
