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

In this letter, we consider a single-input multiple-output cognitive wiretap system over
generalized-K channels, where the eavesdropper overhears the transmission from the …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

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(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …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 study investigates the secrecy outage performance of a single‐input multiple‐output
underlay cognitive radio network (CRN) with outdated channel state information (CSI). The …

This paper studies the secure multiple-antenna transmission in slow fading channels for the
cognitive radio network, where a multiple-input, single-output, multieavesdropper (MISOME) …

In this paper, the secure communication of a cognitive radio network (CRN) over Nakagami-
m fading channel is investigated. An underlay protocol is used in the considered network …

This paper considers a single-input-multiple-output underlay cognitive wiretap system over
Nakagami-m channels with generalized selection combining, where confidential messages …

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 …

This paper investigates the joint impact of nodes' mobility and imperfect channel estimates
on the secrecy performance of an underlay cognitive radio vehicular network over Nakagami …
