This letter investigates secrecy performance for cognitive transmissions, where a secondary user (SU) shares same spectrum with a primary user (PU) simultaneously ensuring the …
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 …

In this paper, we investigate the secondary network physical layer security under the outage constraint of the primary user (PU) receiver and interference from the PU transmitter to the …
D Xu, Q Li - IEEE Systems Journal, 2016 - ieeexplore.ieee.org
We consider a cognitive radio network where multiple secondary users (SUs) coexist with a primary user (PU). There exist multiple eavesdroppers (EAVs) who attempt to overhear the …
M Qin, S Yang, H Deng, MH Lee - IEEE Access, 2018 - ieeexplore.ieee.org
This paper investigates the effect of multiuser gain provided by the secondary user selection on the secrecy performance of the primary users. We first propose a simple scheme where …
In this paper, we investigate the physical-layer security of a secure communication in single- input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …
We investigate the secrecy outage performance of maximal ratio combining (MRC) in cognitive radio networks over Rayleigh fading channels. In a single-input multiple-output …
