摘要

【目的】

文章进行仿真研究实验的目的是提高正交频分复用（OFDM）—波分复用（WDM）光纤通信系统的性能，为此提出了正交分组子载波幅度整形（QGSAS）双相位共轭孪生波（dual-PCTW）方案以抑制该类系统的非线性效应，并搭建多种不同条件下的仿真系统以探究该方案的性能。

【方法】

具体的实验方法为：利用Matlab和Optisystem两种软件混合编程，在16和64进制正交幅度调制（QAM）格式下，选取两种QGSAS方案（正弦幅度整形和矩形幅度整形），搭建了3种维度（偏振域、子载波域和时域）的QGSAS dual-PCTW OFDM系统，共涉及12种组合形式。

【结果】

通过仿真分析不同方案下的系统误码率，结果表明：QGSAS dual-PCTW方案可有效提高系统对非线性效应的容忍度；在讨论的几种组合方案中，16QAM下时域方案的dual-PCTW技术对系统有最佳的性能改善；应用QGSAS技术时，矩形幅度整形方案性能优于正弦幅度整形方案。

【结论】

因此可以得到结论：在文章所提方案中，矩形幅度整形方案结合16QAM下的时域方案dual-PCTW技术，可以最有效地抑制OFDM-WDM系统的非线性效应。

Abstract

【Objective】

In this paper

the objective of the research is to improve the performance of Orthogonal Frequency Division Multiplexing (OFDM)-Wavelength Division Multiplexing (WDM) optical fiber communication system. a Quadrature Grouped Subcarrier Amplitude Shaping (QGSAS) dual-Phase Conjugate Twin Waves (dual-PCTW) scheme is proposed

which can suppress the nonlinear effect of the systems. In addition

the simulation systems under different conditions are built to explore the performance of the scheme. The specific experimental methods are as follows.

【Methods】

With the mixed programming of Optisystem and Matlab

a QGSAS dual-PCTW OFDM system is simulated based on 16-ary and 64-ary Quadrature Amplitude Modulation (QAM) formats. Two kinds of QGSAS (sinusoidal amplitude shaping

rectangular amplitude shaping) and three dimensions dual-PCTW (time domain

polarization domain

sub-carrier domain) are adopted for the system to form 12 different combinations.

【Results】

The simulation results show that the QGSAS dual-PCTW scheme can effectively suppress the nonlinear effects in the system. In several combination schemes discussed

the 16QAM dual-PCTW scheme in time domain has the best performance. When the QGSAS technology is used

the scheme of rectangular amplitude shaping is better than the sinusoidal amplitude shaping.

【Conclusion】

Therefore

it can be concluded that in the scheme studied in this paper

the rectangular amplitude shaping scheme combined with the time domain scheme dual-PCTW technology under 16QAM can effectively suppress the nonlinear effect of OFDM-WDM system.
