摘要

CO-OFDM（相干光正交频分复用）系统具有高效的数字信号处理能力

是未来100Gbit/s高速光传输实现的备选方案。文章对PDM-CO-OFDM（基于PDM（偏分复用）技术的CO-OFDM）系统的传输机理及数学模型进行了分析

在此基础上对系统联合信号均衡算法进行了讨论

并通过数值仿真加以验证。结果表明

PDM-CO-OFDM系统采用联合信号均衡可有效抑制PDM带来的噪声影响

实现偏振信号的不敏感接收。在不需偏振控制器的条件下

通过SMF（单模光纤）传输960km后

系统Q值较CO-OFDM系统降低了0.3dB。

Abstract

With highly-efficient digital signal processing capability

the Coherent Optical Orthogonal Frequency Division Multiplexing（CO-OFDM）system is considered as a promising option for future 100Gbit/s high-rate optical transmissions.This paper analyzes the transmission mechanism and mathematical model of the Polarization Division Multiplexing（PDM）-based COOFDM technology and on this basis discusses a joint signal equalization algorithm for this system.Numerical simulation results verify that using this algorithm

the said system can effectively suppress the noise effects brought about by PDM

realizing the insensitive reception of the polarization signals.Specifically

the systemQvalue is lowered by only 0.3dB than the CO-OFDM system after 960 km single-mode fiber transmission without any polarization controller.
