“…20 proposed an analytical framework for double-hop amplify-and-forward NLOS UV cooperative relay and derived closed expressions of the outage probability and average symbol error rate. Reference 21 adopted an optimal relay selection approach by decoding and forwarding relays based on the channel state information for NLOS UV communication in the presence of log-normal channels. Reference 22 considered a multihop UV system with decoding and forward relay and analyzed its performance under lognormal (LN) turbulence.…”

This paper proposes a method to study the transmission characteristics of ultraviolet turbulent channels, by considering the variation of atmospheric refractive index structure parameters along transmission paths. This method is adopted in a Monte Carlo simulation to analyze the transmission characteristics of ultraviolet light when the communication nodes are mobile. The analysis focuses on the influence of the moving speed and direction of the receiver on path loss under long-distance and atmospheric turbulence conditions. The simulation results show that, when the altitude increases, atmospheric refractive index structure parameters show a decreasing trend, and the path loss of the system decreases. With or without turbulence, when the receiver moves away from the transmitter in a horizontal plane, the received signal strength always decreases as the moving speed increases; and vice versa. When the receiver moves along the vertical axis, the signal strength increases as the moving speed increases. With the presence of atmospheric turbulence, the received signal strength attenuates significantly, compared with the case with no turbulence. When the receiver moves along the vertical axis, the path loss is higher compared with the situation when the receiver moves on the horizontal plane.

“…This form of communication in the atmospheric surface layer often employs the UV radiation. Theoretical studies of the process of optical communication based on scattered radiation evaluate the effect of the following factors on the communication quality: (1) radiation attenuation along the path, in particular, due to turbulence [1][2][3] and (2) the level of inter-symbol interference [4,5] and various types of optical signal modulation [6][7][8]. The experimental studies concentrate on (1) limited range [9,10] and (2) capability to communicate with unmanned aerial vehicles (UAVs) [11], vehicles [12], etc.…”

The results of field experiments on atmospheric optical communication based on scattered laser radiation in the UV range are reported and briefly discussed. In addition, the effect of the ozone concentration on the probability of receiving error symbols is estimated. The characteristics of the transmit/receive equipment used in the experiments and the experimental results obtained with this equipment in daytime at a wavelength λ=255 nm are presented. The stable communication at a baseline distance of 1.3 km in the presence of precipitation in the form of rain and at the high concentration of water vapor in the atmosphere was obtained. A strong positive correlation between the ozone concentration and the symbol-error probability was found.

“…Благодаря существенному рассеянию, для связи в приземном слое атмосферы используют, как показывает анализ публикаций, ультрафиолетовое излучение. В рамках теоретических исследований процесса оптической связи на рассеянном излучении оцениваются влияние на ее качество: 1) потерь на трассе, в том числе и за счет турбулентности [1][2][3]; 2) межсимвольных помех [4,5], а так же различных типов модуляции оптического сигнала на ее производительность [6][7][8]. В рамках экспериментальных исследований этой связи оцениваются: 1) предельное дальнодействие [9,10]; 2) возможность связи с беспилотными летательными аппаратами (БПЛА) [11], автотранспортом [12] соответственно из [10]:…”

В работе представлены и кратко обсуждаются результаты полевых экспериментов по атмосферной оптической связи на рассеянном лазерном излучении в УФ диапазоне. Показано, что в дневное время суток на длине волны λ=255 нм возможна стабильная связь на базовом расстоянии 1,3 км при наличии осадков в виде дождя и высокой концентрации водяного пара в атмосфере. Эксперименты показали, что на базовом расстоянии 2,6 км в ночное время возможна только нестабильная связь. Приведены характеристики приемо-передающих блоков, использованных в экспериментах.
