Abstract

In this letter, we investigate the performance improvement of binary polarization shift keying (2-PolSK) transmission over the ultraviolet scattering channels. To this end, we statistically characterize the cross-polarization discrimination (XPD) of the channel when horizontal and vertical polarization are individually transmitted. The received polarization is characterized in terms of its statistical moments and approximating it to be truncated Gaussian distributed. To enhance 2-PolSK error performance, we propose XPD-dependent optimal thresholding. Electric field Monte Carlo (EFMC) simulation is used to realize the channel. The bit error rate results show a significant improvement through our proposed approach as compared to the conventional symmetric thresholding-based signal reception.

UV散射信道中2-PolSK的性能优化

在这篇文章中，我们研究了在紫外散射通道上二元偏振移键控（2-PolSK）传输性能的改进。为此，我们统计表征了当水平和垂直极化分别传输时信道的交叉极化辨别（XPD）。接收极化用其统计矩表示，并近似为截尾高斯分布。为了提高2-PolSK误差性能，我们提出了依赖于xpd的最优阈值。采用电场蒙特卡罗（EFMC）仿真实现了该信道。与传统的基于对称阈值的信号接收相比，我们提出的方法在误码率上有了显著的改善。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
