A correlated phase-and-additive-noise (CPAN) mismatched model is developed for wavelength division multiplexing over optical fiber channels governed by the nonlinear Schrödinger equation. Both the phase and additive noise processes of the CPAN model are Gauss-Markov whereas previous work uses Wiener phase noise and white additive noise. Second order statistics are derived and lower bounds on the capacity are computed by simulations. The CPAN model characterizes nonlinearities better than existing models in the sense that it achieves better information rates. For example, the model gains 0.35 dB in power at the peak data rate when using a single carrier per wavelength. For multiple carriers per wavelength, the model combined with frequency-dependent power allocation gains 0.14 bits/s/Hz in rate and 0.8 dB in power at the peak data rate.

降低光纤通道容量的不匹配模型

相关相位加性噪声 (CPAN) 失配模型被开发用于由非线性薛定谔方程控制的光纤通道上的波分复用。CPAN 模型的相位和加性噪声过程都是高斯-马尔可夫,而以前的工作使用维纳相位噪声和白加性噪声。导出二阶统计数据,并通过模拟计算容量的下限。CPAN 模型比现有模型更好地表征非线性,因为它实现了更好的信息速率。例如,当每个波长使用单个载波时,该模型在峰值数据速率下获得 0.35 dB 的功率。对于每个波长的多个载波,该模型与频率相关的功率分配相结合,在速率上获得了 0.14 比特/秒/赫兹,在峰值数据速率下获得了 0.8 分贝的功率。
