Abstract

In this paper, the authors investigate two-way hybrid satellite-terrestrial relaying networks, where a satellite communicates with a terrestrial user through a terrestrial half-duplex amplify-and-forward (AF) relay, and propose a novel semi-blind AF strategy, which utilizes the statistical channel state information (CSI) pertaining to the satellite-relay link and the instantaneous CSI pertaining to the user-relay link, avoiding numerous CSI training pilots of the satellite-to-relay link and possessing low implementation complexity, thus improving the energy efficiency of the satellite. Exact closed-form outage expressions for the proposed strategy are derived, which can provide the important performance reference. Simulation results confirm the validity of theoretical analysis and demonstrate that the power allocation between the satellite and the user and placing the relay close to the user, which is a reasonable configuration for practical systems, can efficiently guarantee the outage performance of the proposed strategy.
