Characteristics of non-line-of-sight polarization ultraviolet communication channels

Abstract

This paper investigates characteristics of polarization in non-line-of-sight (NLOS) ultraviolet (UV) communication channels based on a vectorized polarization-sensitive model of NLOS multiple-scatter propagation. The degree of polarization has been analyzed from the following factors: elevation angles, beam angle, field-of-view, off-axis angles, and baseline distance, etc. We draw conclusions that will guide the design of polarization multiplexing technology in NLOS UV communication systems. Outdoor experimentation has validated that this technology is useful to improve the data rate.

Polarization detection in deep-ultraviolet light with monoclinic gallium oxide nanobelts

“…In addition, by using the polarization modulation, the data transmission rate of DUV communication would be signicantly improved. [1][2][3][4] Some of the reports on polarization detection with critical parameters are listed in Table 1. These reports can be classied into two categories according to their detection mechanisms.…”

Achievable Rate Bounds on Poisson Channel with a Sample-Based Practical Photon-Counting Receiver

“…Optical scattering communication is typically developed in the ultraviolet (UV) spectrum due to solar blind region (200nm-280nm) where the solar background radiation is negligible. On the UV scattering communication channel characterization, extensive studies based on Monte Carlo simulation [3], [4], theoretical analysis [5], [6], [7] and experimental results [8], [9], [10] show that the atmospheric attenuation among scattering channel can be extremely large, especially for long-range transmission. Hence, it is difficult to detect the received signals using conventional continuous waveform receiver, such as photon-diode (PD) and avalanche photon-diode (APD).…”
