In this paper, we present experimental results for characterizing turbulence phenomena in free-space optical (FSO) communication under laboratory controlled conditions. Collected data is used statistical determination of the probability density function (PDF) irradiance signal fluctuations. literature, there are a number empirical models variety regimes. Thus, obtained PDF compared with selecte...

Free Space Optical (FSO) communication systems have extensively invaded the speed of smart city evolution due to current surge in demand for wireless spots that can match recent challenges high technical leaps evolution. As number users is vastly increasing throughout all networks form machines, devices, and variously distinct objects, FSO a hugely recommended robust system mitigates lot RF dis...

A free-space communication scheme is proposed based on orbital angular momentum (OAM) states and pulse position modulation (PPM). It can not only improve the channel capacity, but also be suitable for single-photon detection to realize in case of ultra-weak light. parallel coding method high-capacity low bit error rate (BER) under high background. Theoretical simulation experimental results sho...
