Robust Joint Beamforming and Jamming for Secure AF Networks: Low-Complexity Design PROJECT TITLE :Robust Joint Beamforming and Jamming for Secure AF Networks: Low-Complexity DesignABSTRACT:This paper investigates the physical-layer security issue of an amplify-and-forward (AF) relay network. We have a tendency to propose a joint cooperative beamforming (CB) and cooperative jamming (CJ) style that is sturdy to the imperfect channel state data (CSI) of the multiple multiantenna eavesdroppers. The objective is the worst-case secrecy rate maximization (WCSRM). Primarily based on the inner convex approximation and semidefinite relaxation (SDR) technique, the original nonconvex drawback is transformed into a sequence of approximate convex issues, which can be solved conveniently. The proposed strong style guarantees to converge to a Karush–Kuhn–Tucker (KKT) answer and is efficient in computational complexity. Furthermore, we tend to prove that SDR perpetually features a rank-1 solution, which identifies that SDR is tight. Simulations demonstrate the validity of the proposed strategy.
