Abstract :
In this paper, the performance analysis of a subcarrier intensity-modulated free-space optical (SIM-FSO) communication system is investigated for the generalized channel model known as M-distribution channel, and new closed-form analytical expressions are derived for the outage probability and average channel capacity of the system. Since, the turbulence-induced fading model considered is the generalized one, the expressions obtained can be applied for performance analysis of SIM-FSO communication systems for most of the previously existing channel models.
