Abstract
Atmospheric turbulence causes intensity and phase disturbances on the wavefront of electromagnetic waves propagation through it that can seriously degrade the reliability of free- space optical communication links. This paper deals with the estimation of the statistics for power fades resulting from the combined effects of distortion of the receiving system instantaneous point-spread function and from the fluctuations of the collected power arising from wavefront intensity fluctuations. Fractal techniques are employed to simulate the turbulence-induced point-spread function distortions, while a log-normal model is assumed for the collected-power fluctuations. The reduction in the cumulative probability of losses due to these two effects through spatial diversity using a multiaperture receiver configuration is assessed.
