论文摘要
非线性Schrodinger方程的时域扰动模型用于研究单个极化上的波长划分多路复用通信。该模型解释了（a）与独立和统一的星座点相比，恒定组件代码为什么即使在不使用恒定组件代码的情况下使用载波恢复算法获得了相似的收益，因此信号与噪声比的改善和均匀选择。
A time-domain perturbation model of the nonlinear Schrodinger equation is used to study wavelength-division multiplexed communication over a single polarization. The model explains (a) why constant-composition codes offer an improvement in signal to noise ratio compared with independent and uniform selection of constellation points and (b) why similar gains are obtained using carrier recovery algorithms even without using constant-composition codes.
