We consider a secure overlay cognitive radio network with an eavesdropper wherein a multi-
antenna secondary transmitter performs transmission in primary spectrum, on the condition …

In this paper, we consider a cooperative multi-hop secured transmission protocol to underlay
cognitive radio networks. In the proposed protocol, a secondary source attempts to transmit …

In this paper, we consider a cooperative cognitive radio non-orthogonal multiple access
network, where a secondary transmitter (ST) assists transmission of a primary source …

In this paper, we investigate the secrecy performance of cognitive radio networks (CRNs)
with full-duplex (FD) relaying over Rayleigh channels, where the secondary transmitter …

This paper investigates the secrecy performance of amplify-and-forward (AF)-relaying
cooperative cognitive radio networks (CCRNs) over Rayleigh-fading channels. Specifically …

In this paper, we design a new collaboration interference (CI) transmission scheme for
overlay cognitive full-duplex wireless wiretap networks, where a full-duplex secondary user …

In this paper, we investigate a new cooperative paradigm to provide information security for
the primary system in cognitive two-way networks where the two-way secondary system can …

In this paper, we investigate cooperative secure communications in a four-node cognitive
radio network where the secondary receiver is treated as a potential eavesdropper with …

In this paper, we investigate the secrecy performance of a multiantenna cognitive wiretap
network, where the secondary transmitter (Alice) communicates with the secondary receiver …

In this paper, we analyze the secrecy performance of multi-antenna cognitive wiretap
network, where the secondary transmitter (Alice) communicates with the secondary receiver …
