Secure Beamforming for MIMO-NOMA-Based Cognitive Radio Network

IEEE Communications Letters, 2018
Cognitive radio network (CRN) and non-orthogonal multiple-access (NOMA) play the crucial roles in the fifth generation wireless communication systems. However, the physical-layer security still remains quite challenging.
