Joint Optimization of AN-Aided Transmission and Power Splitting for MISO Secure Communications With SWIPT

ABSTRACT:

For simultaneous wireless info and power transfer (SWIPT), secure communication is a crucial issue. During this letter, we have a tendency to consider a wireless multiple-input-single-output secure communication system with SWIPT overheard by multiple multi-antenna eavesdroppers. In the system, a transmitter employs artificial noise (AN)-aided transmission and a legitimate receiver employs power splitting (PS) to reap energy. Our objective is to jointly style AN-aided transmission and PS theme that maximizes achievable secrecy rate beneath transmit power constraint and energy harvesting constraint. We have a tendency to propose to incorporate an equality constraint to convert the constraint on info rate from transmitter to eavesdroppers into linear matrix inequalities. Replacing the equality constraint with a convex constraint and a concave constraint, we have a tendency to propose to use constrained concave convex procedure primarily based algorithm to find a native optimum of the problem. Simulation results demonstrate that the proposed joint optimization of AN-aided transmission and PS theme outperforms the non-AN-aided one.
