Cooperative communication combining non-orthogonal multiple access (NOMA) and
cognitive radio is a rapidly growing technique for wireless networks and beyond 5G Still …

In this paper, we investigate the physical layer security (PLS) of an overlay cognitive non-
orthogonal multiple access (NOMA) system with control-jamming (CJ) under Nakagami-m …

In this paper, we study the physical layer security for underlay cognitive radio network in the
presence of an eavesdropper that tries to intercept the secondary transmission. Specifically …

Recently, the combination of cognitive radio networks with the nonorthogonal multiple
access (NOMA) approach has emerged as a viable option for not only improving spectrum …

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 …

In this paper, the problem of security in multiple input multiple output (MIMO) system has
been analysed in the presence of an eavesdropper in cognitive radio networks. Multiple …

Aiming for ultra-reliable low-latency wireless communications required in industrial internet
of things (IIoT) applications, this paper studies a simple cognitive radio non-orthogonal …

This paper investigates the effect of multiuser gain provided by the secondary user selection
on the secrecy performance of the primary users. We propose a simple secondary user …

In this paper, an underlay cooperative cognitive network using a non-orthogonal multiple
access (UCCN-NOMA) system is investigated, in which the intermediate multiple relays help …

In this paper, we consider a multi-hop decode-and-forward (DF) relaying transmission in
underlay cognitive radio networks. Considering the presence of an eavesdropper that …
