Performance evaluation of modulation and multiple access schemes in ultraviolet optical wireless connections for two atmosphere thickness cases.

Journal of the Optical Society of America. A, Optics, image science, and vision

Raptis N, Pikasis E, Syvridis D.
PMID: 27505663
J Opt Soc Am A Opt Image Sci Vis. 2016 Aug 01;33(8):1628-40. doi: 10.1364/JOSAA.33.001628.

The exploitation of optical wireless communication channels in a non-line-of-sight regime is studied for point-to-point and networking configurations considering the use of light-emitting diodes. Two environments with different scattering center densities are considered, assuming operation at 265 nm. The...
