Abstract

A probability-based model is developed to describe cross phase modulation in multichannel multilevel amplitude/phase modulated coherent systems. Standard deviation of nonlinear phase-shift is evaluated in 16-QAM coherent systems accordingly and by numerical simulation for different values of chromatic dispersion and symbol rate. Furthermore, an error analysis is provided to evaluate the accuracy of the model which demonstrates maximum relative error of 12% in the field of interest.

摘要

开发了一种基于概率的模型来描述多通道多级幅度/相位调制相干系统中的交叉相位调制。相应地，在16-QAM相干系统中评估了非线性相移的标准偏差，并针对不同的色散值和符号率进行了数值模拟。此外，还提供了误差分析以评估模型的准确性，该模型在感兴趣的领域中显示出最大相对误差为12%。
