摘要

Shehadeh和Kschischang最近的工作通过精心选择基于正交设计的预编码和干扰消除，为具有极化相关损耗（PDL）的信道提供了一种在常见建模假设下的简单容量实现方案。这封信通过基于仿真的演示扩展了这项工作，表明该方案在具有chase解码的扩展汉明内码而不是原始工作中考虑的近容量内码的16-QAM的高度实用设置中仍然非常有效地减轻PDL。还提供了该方案的另一种接近最优的变体，只需要一个内部代码而不是两个，并且在没有PDL的情况下没有任何损失，使其更加实用。

Polarization-Dependent Loss Mitigation via Orthogonal Design Precoding and Interference Cancellation

Recent work by Shehadeh and Kschischang provides a simple capacity-achieving scheme for channels with polarization-dependent loss (PDL) under common modeling assumptions via a careful choice of orthogonal-design-based precoding and interference cancellation. This letter extends that work with a simulation-based demonstration showing that this scheme remains highly effective at mitigating PDL in the highly practical setting of 16-QAM with Chase-decoded extended Hamming inner codes rather than the near-capacity inner codes considered in the original work. An alternative near-optimal variation of this scheme is also provided requiring only one inner code rather than two and suffering no penalty in the absence of PDL, making it much more practical.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
