主　　题：secrecy rate information-theoretic security amplify-and-forward (AF) dual-hop relay wiretap channel 

摘      要：An amplify-and-forward(AF) dual-hop relay is proposed for secure communication within Wyner s wiretap *** on an information-theoretic formulation,the average secrecy rate is characterized when two legitimate partners communicate over a quasi-static fading *** analysis and simulation results show that both cooperative strategies of average power scaling(APS) and instantaneous power scaling(IPS) are proved to be able to achieve information-theoretic security,and eavesdropper is unable to decode any information.
