Secure Energy Efficiency for NOMA Based Cognitive Radio Networks With Nonlinear Energy Harvesting
In order to improve the spectrum efficiency and secrecy energy efficiency, in this paper, we propose a non-orthogonal multiple access (NOMA)-based secure scheme for cognitive radio networks. In the proposed scheme, the secondary users harvest energy from the radio-frequency signals to securely trans...
