Non-Line-of-Sight Ultraviolet Communication Performance in Atmospheric Turbulence

Non-Line-of-Sight （NLOS） Ultrav- iolet （UV） communication uses the atmosph- ere as a propagation medium. As the commu- nication range increases, turbulence becomes a significant atmospheric process that affects the propagation of optical waves. This paper pre- sents a more accurate NLOS channel model by considering turbulence-induced Scintillation Att- enuation （SA）. Then, the Bit Error Rate （BER） during turbulence of the NLOS UV commu- nication system with On-Off Keying （OOK） modulation and Maximum Likelihood （ML） detection is analysed and compared with that in free space without turbulence. The BER dependence is also analysed for different fac- tors, including the refractive index structure parameter, transceiver range, pointing angles, transmitted power, and data rate.
