Performance Analysis of Dual-Hop Satellite Relaying

Satellite communication is considered as an indispensable method in the future seamless wireless networks. In this paper, we first propose an opportunistic user scheduling scheme for a dual-hop satellite relaying with decode-and-forward (DF) protocol. Then, by supposing that the satellite links experience Shadowed-Rician (SR) fading, we derive the closed-form outage probability (OP) expression for the considered system. Finally, computer simulation results are given to demonstrate the validity of the performance analysis and verify that the OP of the dual-hop satellite relaying system can be improved through multi-user diversity. Our work is helpful for the engineers to design a practical satellite network.
