摘要

设计了一种适用于偏振复用相干解调光纤通信系统的色散均衡器,用于补偿信道传输的色散损伤。该均衡器采用半码元间隔的蝶形有限脉冲响应滤波器结构,与此结构配合的自适应算法分别采用最小均方算法和递归最小二乘算法。通过仿真实验,分析了两种算法对残留色度色散和偏振模色散的补偿容限。仿真结果表明,递归最小二乘算法的补偿效果优于最小均方算法,它可以同时补偿1760 ps/nm的残留色度色散和104.9 ps偏振模色散引起的差分群时延,比同等条件的最小均方算法提升性能2.23 dB。

Abstract

A dispersion equalizer is designed to compensate dispersions of polarization multiplexing coherent fiber optics communication systems. The proposed equalizer is realized with fraction spaced butterfly finite impulse response (FIR) structure and the corresponding adaptive algorithms are least mean square (LMS) and recursive least squares (RLS), respectively. The residual chromatic dispersion(CD) and polarization mode dispersion (PMD) tolerances of both algorithms are analyzed by simulation. The simulation results show that RLS can compensate 1760 ps/nm residual CD and 104.9 ps differential group delay (DGD) simultaneously and it has 2.23 dB promotion than LMS.
