Atmospheric channel for bistatic optical communication: Simulation algorithms
Three algorithms of statistical simulation of the impulse response (IR) for the atmospheric optical communication channel are considered, including algorithms of local estimate and double local estimate and the algorithm suggested by us. On the example of a homogeneous molecular atmosphere it is demonstrated that algorithms of double local estimate and the suggested algorithm are more efficient than the algorithm of local estimate. For small optical path length, the proposed algorithm is more efficient, and for large optical path length, the algorithm of double local estimate is more efficient. Using the proposed algorithm, the communication quality is estimated for a particular case of the atmospheric channel under conditions of intermediate turbidity. The communication quality is characterized by the maximum IR, time of maximum IR, integral IR, and bandwidth of the communication channel. Calculations of these criteria demonstrated that communication is most efficient when the point of intersection of the directions toward the source and the receiver is most close to the source point.

Application of fuzzy synchronization in the NLOS UV communication system
To ensure the effective operation of UV-C communication systems in the non-line-of-sight (NLOS) mode, synchronization between an optical transmitter and an optical receiver is often required. The complex noise-like nature of the signal on the receiving side of the UV-C communication system determines the relevance of using various methods for synchronizing UV-C communication systems based on the neuro-fuzzy approac
Methodology for estimating the energy reserve of a mobile adhoc communication network with UV-C channel
Communication systems of the solar-blind ultraviolet range UV-C from 200 to 280 nm provide the possibility of communication in the absence of line of sight due to the strong scattering of UV radiation in the atmosphere. For the effective use of UV-C communication systems, an adequate assessment of the energy budget of the UV channel is necessar
