چکیده مقاله:
These days, the security of wireless networks is a major concern for both providers and users. This study focuses on a cooperative wireless system with a full-duplex multipleantenna relay in the presence of an eavesdropper and a jammer. Our aim is to examine the impact of full-duplex multiple-antenna relay on improving system security, by using the zero-forcing based beamforming design. To this end, we design the receive and transmit beamformer vectors and accordingly derive the average secrecy rate of the considered system. Simulation results are presented to validate the derived analysis and to show the impact of the various parameters on the system performance.
