Experimental indoor validation of weak intensity fluctuations over free-space optical communication link

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 selected from bibliography order to describe properly properties real turbulent channel and help improving FSO system performance calculation. overall, analysis has shown that given constraints fit well exponentiated Weibull model.
