| 摘 要： | 基于正交频分复用(OFDM)与波分复用(WDM)的基本原理,构建了一套基于OFDM技术的WDM传输系统的系统模型,并对其相关系统性能进行了理论分析。基于维纳相位噪声模型,文章对OFDM系统中相位噪声引起的公共相位误差和子载波间干扰进行了分析,在此基础上深入分析了基于交叉复用OFDM技术的OFDM子载波间干扰的消除方法,降低相位噪声对系统性能的影响。最后结合理论分析结果对系统模型的相关性能进行模拟计算,分析结果表明:采用交叉复用OFDM技术在降低相位噪声对OFDM系统性能的影响的同时,提高了系统的信号处理能力。

| Abstract: | Based on orthogonal frequency division multiplexing(OFDM) and wavelength division multiplexing (WDM) principle, a model of OFDM-WDM transmission system was designed. The common phase error and inter-carrier interference in OFDM system caused by the phase noise were analyzed using Wiener phase noise model. In order to suppress the phase noise, a general inter-carrier interference suppression scheme was provided based on the interleaved OFDM technology. The analytical and numerical results show that this interleaved OFDM technology effect in reducing inter-carrier interference on the performance of OFDM system, at the same time, the signal processing ability of the system. |
