Description
Summary:With rapid advances of solar blind ultraviolet LED and ultraviolet detecting technology in recent years, ultraviolet communication gradually becomes a research hotspot due to its inherent advantages： low solar background noise, non-line-of-sight（NLOS） and good secrecy. The strong scattering characteristics in atmospheric render ultraviolet waveband the ideal choice for achieving NLOS optical communication. This paper reviews the research history and status of ultraviolet communication both in China and abroad, and especially introduces three main issues of ultraviolet communication： channel model, system analysis and design, light sources and detectors. For each aspect, current open issues and prospective research directions are analyzed.
