This paper develops a tractable analysis framework to evaluate the reliability and security
performance of cooperative non-orthogonal multiple access (co-NOMA) in cognitive …

Cognitive radio (CR) technology can be used as a key technology for wireless
communication to integrate heterogeneous networks, increasing channel capacity and …

Underlay mode of cognitive radio networks (CRNs) permits secondary users (SUs) to
simultaneously operate with primary users (PUs), inducing mutual interference between …

This paper studies the physical layer security (PLS) in an underlay cognitive radio (CR)
network. Under an interference constraint set by the primary user, we propose a secure …

This paper investigates physical layer security of non-orthogonal multiple access (NOMA) in
cognitive radio (CR) networks. The techniques of NOMA and CR have improved the …
