论文摘要
在本文中，我们分析了偏振算法在具有快速状态（SOP）旋转和极化依赖性损失（PDL）的光传输系统中的有效性。尽管文献中的大多数梯度下降（GD）算法可能需要在通道条件发生变化时进行步长调节，但我们提出了跟踪算法，这些算法可以在没有参数调整的情况下执行类似或更好的性能。与基于GD的算法相比，数值仿真结果表明，所提出的算法对SOP和PDL漂移的鲁棒性更高，这使得它们有望在SOP可能会迅速漂移的空中纤维链路中使用，因此可以追溯到挑战。
In this paper, we analyze the effectiveness of polarization tracking algorithms in optical transmission systems suffering from fast state of polarization (SOP) rotations and polarization-dependent loss (PDL). While most of the gradient descent (GD)-based algorithms in the literature may require step size adjustment when the channel condition changes, we propose tracking algorithms that can perform similarly or better without parameter tuning. Numerical simulation results show higher robustness of the proposed algorithms to SOP and PDL drift compared to GD-based algorithms, making them promising candidates to be used in aerial fiber links where the SOP can potentially drift rapidly, and therefore becomes challenging to track.
