Abstract

In this paper, we propose a hybrid cooperative beamforming and jamming scheme to enhance the physical-layer security in the two-way relay network with an eavesdropper and a primary receiver. Cooperative beamforming and jamming are designed to maximize the secrecy rate with a total transmit power con
