	%X The performance of Decode and Forward (DF)
multihop Free Space Optical ( FSO) scheme deploying Multiple Input
Multiple Output (MIMO) configuration under Gamma-Gamma (GG)
statistical distribution, that adopts M-ary Pulse Position Modulation
(MPPM) coding, is investigated. We have extracted exact and
estimated values of Symbol-Error Rates (SERs) respectively. A
closed form formula related to the Probability Density Function
(PDF) is expressed for our designed system. Thanks to the use
of DF multihop MIMO FSO configuration and MPPM signaling,
atmospheric turbulence is combatted; hence the transmitted signal
quality is improved.
