The AF relay ensures the transmission of the signal in the presence of one passive eavesdropper where all channels are assumed to undergo a Rician fading. In this context, analytical and asymptotic expressions for Secrecy Outage Probability (SOP) are derived. To verify our theoretical analysis, numerical results are presented, showing the effect of different Rician factors on secrecy performance. © 2019 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.https://www.ieee.org/publications/rights/rights-policies.htmlAmplify-and-forwardCooperative NOMARician fadingSecrecy Outage probabilityComputer networksMobile telecommunication systemsAmplify and-forward relayAsymptotic expressionsNumerical resultsPassive eavesdroppersConference PaperCopyright : 2019 IEEE.
