In limited space scenarios, the antennas in the multiantenna cognitive radio (CR) system are
closely spaced and often experience correlation among them. In this work, the secrecy …

I265 this paper, we investigate the secrecy performance of multi-input single-output and
single-eavesdropper (MISOSE) cognitive radio (CR) networks over correlated fading …

In this paper, the physical layer security in cognitive radio networks (CRNs) is investigated.
We consider an underlay relay assisted CRN consisting of multiple secondary sources …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

This paper investigates physical layer security of underlay cognitive radio networks with
interference constraint over α-μ fading channels. Specifically, in the secondary network, a …

In this paper, physical-layer security (PLS) for an underlay cognitive radio network (CRN)
over cascaded Rayleigh fading channels is studied. The underlying cognitive radio system …

The fifth-generation (5G) communications and beyond are expected to serve a huge number
of devices and services. However, due to the fixed spectrum allocation policies, the need for …

This paper investigates the secrecy performance of a single-input multiple-output (SIMO)
based underlay cognitive radio networks. In particular, a single-antenna secondary …

This work studies the physical layer security performance for Multiple Input Multiple Output
(MIMO) secondary nodes. The proposed model is assumed to operate in underlay Cognitive …

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 …
