This paper investigates the secure performance of multi‐antenna decode‐and‐forward (DF)
relaying networks where the Nakagami‐m fading channel is taken into account. In practice …

Modern wireless technologies confirm the massive connectivity with sufficient data rate in
intelligent transportation systems. Passive attacks may compromise the user's transmission …

In this paper, the physical layer security of underlay cognitive decode-and-forward (DF) relay
networks is investigated, wherein one secondary transmitter (ST) exchanges confidential …

In this paper, we design a new collaboration interference (CI) transmission scheme for
overlay cognitive full-duplex wireless wiretap networks, where a full-duplex secondary user …

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 …

Exact secrecy and end-to-end (e2e) system analyses for cooperative wireless networks
employing a best-relay-selection method with imperfect or outdated channel state …

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

This study suggests an energy‐scavenging capable unlicensed relay not only to retain
communications between an unlicensed sender‐recipient pair in underlay cognitive …

Blind recognition of communication parameters has been studied for various applications
including cognitive radios, non-cooperative communications, electronic warfare, etc. In this …

In this paper, the secrecy outage performance is studied for optimal relay selection (ORS)
schemes with energy harvesting system deployed at the secondary transmitter to improve …
