This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

Physical layer security is an important and timely topic in the research of future wireless
systems and it constitutes a part of the Internet of Things (IoT) notion. IoT oriented systems …

In this paper, the physical layer security of a dual-hop underlay uplink cognitive radio
network is investigated over Nakagami-m fading channels. Specifically, multiple secondary …

In this paper, we consider a multi-input multioutput (MIMO) nonorthogonal multiple access
(NOMA) network consisting of one source and two legitimate users (LUs), so-called near …

This paper investigates the secrecy performance of a multiuser system that utilizes transmit
antenna selection scheme at the base station and adopts threshold-based selection …

We consider a cognitive radio (CR) network with simultaneous wireless information and
power transfer (SWIPT) system having one base station (BS) with multiple antennas that acts …

In this paper, we propose frequency diverse array (FDA) antenna for artificial-noise (AN)
aided secure communication over independent but not necessarily identical distributed …

In this paper, we investigate the secrecy performance of dual-hop randomize-and-forward
(RaF) cognitive wiretap networks over Rayleigh fading channels, in which the RaF relay is …

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(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …
