Abstract :
Error control coding can be used over free-space optical (FSO) links to mitigate turbulence-induced fading. In this paper, we derive error performance bounds for coded FSO communication systems operating over temporally correlated lognormal turbulence fading channels. Our analytical derivations build upon an approximation to the sum of correlated lognormal random variables. The derived bounds are tighter than the previously published results and are valid for a wider range of turbulence conditions. Simulation results are further demonstrated to confirm the analytical results
