Security-Reliability Trade-Offs for Satellite-Terrestrial Relay Networks with a Friendly Jammer and Imperfect CSI

Popis výsledku v původním jazyce

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 decode-and-forward (DF) relaying strategies to give a full picture of the benefits of each method. In this context, we derive the closed-form expressions of the outage probability (OP) and intercept probability (IP) corresponding to AF- and DF-based relaying schemes, which is a high challenge and has not been investigated before. Then, Monte-Carlo simulations are conducted to evaluate the correctness of the mathematical analysis and the effectiveness of the proposed methods. Furthermore, the security and reliability trade-off of the SatTer system and the influences of various system parameters (e.g., satellite&apos;s transmit power, channel estimation errors, relay&apos;s transmit power, fading severity parameter, the average power of light-of-sight, and satellite&apos;s multi-path components) on the system performance are shown.
