Specifically, we consider an FSO communication system which employs a central node equipped with N transmit apertures, each of which aimed to any of the users. Under the assumption of log-normal turbulence channels, we derive closed-form outage capacity and outage throughput expressions for the FSO communication system and demonstrate the effect of the outage probability, number of users and average signal-to-noise ratio on the system performance.engrestrictedAccessconferenceObject14314600038052470003410.1109/CWIT.2015.7255172FSO communicationMultiuser schemeOutage capacityOutage throughputTurbulence channels2-s2.0-84957703193
