	  abstract     = {The performance of hybrid amplify and forward -
decode and forward (AF-DF) hybrid radio frequency/free space
optical (RF/FSO) communication system, that adopts M-ary pulse
position modulation (MPPM) techniques, is analyzed. Both exact
and approximate symbol-error rates (SERs) are derived. The random
variations of the received optical irradiance, produced by the
atmospheric turbulence, is modeled by the gamma-gamma (GG)
statistical distribution. A closed-form expression for the probability
density function (PDF) is derived for the whole above system
is obtained. Thanks to the use of hybrid AF-DF hybrid RF/FSO
configuration and MPPM, the effects of atmospheric turbulence is
mitigated; hence the capacity of combating atmospheric turbulence
and the transmissitted signal quality are improved.},
