摘 要:Deep space communication has been a fundamental guarantee for space exploration but encounters solar scintillation during superior solar *** this paper,a paradigm for deep space-terrestrial free space optical(FSO)/radio frequency(RF)communication is proposed,and the outage probability performance of the dual-hop amplify-and-forward(AF)based FSO/RF communication system is ***,the asymmetric dual-hop channel models are considered,where the Gamma-Gamma distribution characterizes the FSO link between the deep space probe and a relay satellite that undergoes coronal turbulence,while the RF link between the satellite and the terrestrial receiver follows the shadowed-Rician fading model due to the shadowing ***,the closed-form expressions of the outage probability for both channel state information(CSI)-assisted and fixed gain relay systems are presented with the consideration of multiple antennas equipped on the destination,which provide practical insights to the link *** results present the validation of our theoretical expressions and highlight a strategy for the improvement of the outage probability performance for deep space-terrestrial ***,some open issues and research directions that should be further investigated for the actual deep space communication system during superior solar conjunction are identified.
