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 gamma-gamma turbulence channels. We derive a pairwise error probability (PEP) expression and then apply the truncated union bound technique in conjunction with the derived PEP to obtain upper bounds on the bit error rate. Simulation results are further demonstrated to confirm the analytical results.
