中文摘要：

研究了相干光正交频分复用（CO-OFDM）系统中基于射频导频（RF-Pilot）的交叉相位调制（XPM）补偿的关键技术,提出了基于Pilot位置的补偿优化方案,通过理论分析得到了最优Pilot位置的选取原则和Q因子分布规律,仿真结果证明了理论分析的正确性。针对7信道CO-OFDM系统,最优和最差Pilot位置处的系统性能相差1.6d B,在实际设计中应根据具体信道配置和该信道上XPM损伤的分布情况来选取最优的Pilot位置,以提升补偿效果和系统性能。

英文摘要：

The key techniques of RF-Pilot based cross-phase modulation （XPM） compensation are studied for CO-OFDM systems. A novel compensation optimization scheme based on the pilot positions is proposed. The optimization principle and the RF-Pilot distribution rules are theoretically analyzed, which are also demonstrated by numerical simulations. For a 7-channel CO-OFDM system, the Q factors for best and worst pilot positions is as high as 1.6dB, which indicates in real applications the optimal pilot positions should be selected according to the specific channel configuration and its XPM distributions, in order to improve the compensation efficiency and system performance.
