Free Space Optical (FSO) communication systems is a high bandwidth access technique which is gaining widespread attention compared to its wired communication counterparts. A major disadvantage in FSO links is the turbulence induction fading which severely degrades the link performance. To overcome this turbulence-induced fading, spatial diversity is used i.e. use of multiple laser transmitters and receivers, this type of system is commonly termed as Multiple-Input Multiple-Output (MIMO) systems. In this paper, the authors investigate the outage probability and diversity gain of MIMO system with different misalignment fading conditions, over a slow turbulence-fading channel.
