Cooperative Secure Transmission in MISO-NOMA Networks

Cooperative Secure Transmission in MISO-NOMA Networks

In this paper, we investigate cooperative secure transmission in non-orthogonal multiple access (NOMA) networks where a source (Alice) intends to transmit confidential messages to one legitimate user with high-level security requirement (LU1), and serve another normal one (LU2) simultaneously. In or...
