We consider an FSO cooperative diversity system with a single decode-and-forward relay and a line-of sight link between the source and the destination. Focusing on high signal-to-noise ratio (SNR) regime, we develop performance characterizations in terms of outage probability, outage diversity and coding gains, and diversity-multiplexing tradeoff (DMT). Our results demonstrate that cooperative diversity improves the performance of FSO communications by bringing diversity advantages.engrestrictedAccessconferenceObject1500031700910046410.1109/VTCFall.2012.6399336Cooperative communicationDecode and forward communicationDiversity receptionMultiplexingOptical linksProbability2-s2.0-84878947256
