Abstract :
In this letter, the transmission of signals in a hybrid satellite-terrestrial free space optical (FSO) cooperative link is considered. In particular, we address the problem of amplify-and-forward (AF) relaying in a hybrid satellite-terrestrial FSO cooperative link, where a masked destination node receives the relayed transmission from an FSO link. The satellite-relay link is assumed to follow the shadowed-Rician fading, and the irradiance of the FSO link between the relay and destination is assumed to follow the gamma-gamma distribution. The approximate average symbol error rate of the considered AF cooperative scheme for M-ary phase shift keying constellation is derived; analytical diversity order of the hybrid cooperative system is also obtained.
