In this paper, we propose a joint channel allocation and power control algorithm by using
cognitive radio non-orthogonal multiple access (CR-NOMA) for femtocell users (FUs). The …

Non-orthogonal multiple access (NOMA) has been developed as a key multi-access
technique for 5G. However, secure transmission remains a challenge in NOMA. Especially …

Non-orthogonal multiple access (NOMA) has been proposed as a promising multiple access
approach for 5G mobile systems because of its superior spectrum efficiency. However, the …

In this paper the transmission security for multiuser multi-input single-output (MU-MISO)-Non-
