In this paper, we consider the physical-layer security for the primary system in an underlay
cognitive radio model which comprises of a primary source–destination pair, a secondary …

In this paper, we investigate the impact of diversity and antenna correlations on the secrecy
capacity and outage performance of a cognitive radio multicast network over Nakagami-m …

The presence of correlated and imperfect channel state information (CSI) affects the secrecy
performance of cognitive radio networks (CRN). In this paper, we propose a physical layer …

This paper investigates the secrecy outage performance of underlay cognitive radio
networks, in which a source in a secondary system transmits its confidential information to a …

The authors study the secure transmission design in random cognitive radio networks where
the primary users, the secondary users and the eavesdroppers are randomly distributed …

In this paper, we investigate the secrecy outage performance of maximal ratio combining
(MRC) in cognitive radio networks (CRNs) over Rayleigh fading channels. In a single input …

In this paper, the secrecy outage probability (SOP) of an energy harvesting aided underlay
single input multiple output cognitive radio network under the multiple eavesdroppers is …

We examine the secrecy performance of the receive antenna selection scheme in
interference-limited underlay cognitive radio network (CRN) where the antenna that results …

In this study, the physical layer security for cognitive radio network (CRN) will be
investigated in which a secondary user transmitter (SU-Tx) sends confidential information to …

An underlay cognitive radio unit over Nakagami-m fading channel, which consists of a
source S, a secondary user (SU), and an eavesdropper who wants to eavesdrop the …
