Abstract

In this paper, the average capacity of free-space optical (FSO) links over Gamma-Gamma turbulence channels with pointing errors is investigated. A FSO communication system using intensity modulation/direct detection (IM/DD) with on-off keying (OOK) is considered. Capacity performance is evaluated under various turbulence strengths and misalignment fading conditions. Further, effect of beam width, jitter variable and transmitted optical power on the average capacity is analyzed. Numerical examples are provided to demonstrate adverse effects of atmospheric turbulence and pointing errors on the capacity performance of the FSO links.
