论文摘要
在这封信中，我们提出了先前呈现的分析模型的扩展，以扩展在相干光学传输系统中自适应均衡器在相干光传输系统中的输出估算的分析模型，当传输被建模为通用2x2矩阵传输函数，以应用于基于高级调节格式（PM-QQAM）的偏置多重通信。我们介绍该模型，然后在可能的应用环境中广泛测试其准确性。我们的发现显示了一个非凡的协议，在时间域模拟和分析结果之间，最大的SNR差异约为0.5 $ db $。
In this letter, we propose the extension of a previously presented analytical model for the estimation of the signal-to-noise ratio (SNR) at the output of an adaptive equalizer in coherent optical transmission systems when transmission is modeled as a generic 2x2 matrix transfer functions, to be applied to polarization multiplexed communications based on advanced modulation formats (PM-QAM). We present the model and then we extensively test its accuracy on an possible application environment. Our findings show a remarkable agreement, with maximum SNR discrepancies of about 0.5 $dB$ between time-domain simulations and analytical results.
