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 atmospheric turbulence channels, considering the
recently introduced gamma-gamma turbulence model. We derive a pairwise error probability
(PEP) expression and then apply the transfer function technique in conjunction with the
derived PEP to obtain upper bounds on the bit error rate. Simulation results are further …
