Security and Reliability Analysis of Satellite-Terrestrial Multirelay Networks With Imperfect CSI

This article investigates the security and reliability analysis for a novel satellite-terrestrial network. Specifically, satellite attempts to transmit confidential information ground user via support of multiple relay nodes in presence an eavesdropper that tries overhear information. A friendly jammer is deployed improve secure transmission between relays. Furthermore, satellite-to-relay generalized Rician fading channels imperfect channel state are examine general system model. In this context, closed-formed expressions outage probability intercept derived corresponding amplify-and-forward based relaying scheme, which challenging has not been studied before. Finally, exactness mathematical analyses validated through Monte Carlo simulations. effects various key parameters (e.g., estimation errors, satellite's power, relay's number relays, severity parameter) examined.
