Journal ArticleDOI
Secure Multiple Amplify-and-Forward Relaying With Cochannel Interference
TL;DR: It is demonstrated that the all selection criteria achieve full secrecy diversity order N, while the proposed two criteria in this paper outperform the conventional max-min scheme.
Journal ArticleDOI
Secrecy Cooperative Networks With Outdated Relay Selection Over Correlated Fading Channels
TL;DR: An analyticalexpression for the secrecy outage probability (SOP) is derived and the asymptotic expression for the SOP in the high main-to-eavesdropper ratio regime is derived in order to study the impact of both channel correlation and outdated relay selection on the secrecy performance.
