Turbulence modeling for non-line-of-sight ultraviolet scattering channels

Abstract

ABSTRACT Recently ultraviolet (UV) scattering channels have received renewed interest for non-line-of-sight (NLOS) communication. Monte Carlo simulations and field experiments have yielded valuable results to predict channel path loss and impulse response at relatively short ranges, critical for communication link analysis. However, as communication range increases, the effect of turbulence becomes pronounced and inevitably induces additional impairments to system performance. This paper suggests a turbulence modeling method for NLOS UV channels incorporating the effects of scattering and absorption. The modeling results can be applied to study communication performance.

INTRODUCTION Ultraviolet (UV) communication has received renewed interest due to recent advances in low cost, small size, low power, high reliability and high bandwidth deep UV light emitting diodes (LEDs) and avalanche photodiodes (APDs).
