Energy Efficiency Maximization with Optimal Beamforming in Secure MISO CRNs with SWIPT
In this paper, the optimal beamforming problem of multi-input single-output (MISO) cognitive radio (CR) downlink networks with simultaneous wireless information and power transfer is studied. Due to the nonconvexity of the objective function, the considered nonconvex optimization problem is firstly...
