Abstract

This paper proposes and analyzes the reliability and security trade-off for a satellite-terrestrial (SatTer) relay system. Herein, a satellite sends confidential information to multiple ground users (GUs) with the help of a relay base station (BS) in the presence of multiple eavesdroppers trying to wiretap the information. In particular, a friendly jammer is deployed near the relay BS to improve secure transmissions. Moreover, the non-identical Rayleigh fading channels and imperfect channel state information (CSI) are adopted for a general system model. Then, we consider both amplify-and-forward (AF) and decodeand-forward (DF) relaying strategies to give a full picture of the benefits of each method.
