We consider a cognitive radio network where multiple secondary users (SUs) coexist with a
primary user (PU). There exist multiple eavesdroppers (EAVs) who attempt to overhear the …

Cognitive jammers are able to deploy advanced strategies that degrade the performance of
cognitive radio (CR) user communications. In this study, the authors study the problem of …

Being an important application of spectrum sharing in cellular networks, mobile traffic
offloading, which advocates third-party owners of network resource on unlicensed/licensed …

Resource allocation (RA) for mobile secondary users is considered one of the most
important techniques for designing the next-generation cognitive radio network (CRN). In …

This paper investigates the problem of data transmission for the joint radar and
communication systems (JRCSs). The performance of the JRCS is characterized by data …

This paper considers a cognitive radio network with a set of secondary users (SUs) who
share a spectrum band licensed to a primary user (PU). The PU is assumed to be …

This paper considers an underlay cognitive radio network with a full‐duplex cognitive base
station and sets of half‐duplex downlink and uplink secondary users, sharing multiple …

In the underlay spectrum sharing approach, cognitive radios have limited coverage area to
keep interference protection for the licensed users. Multiple cooperative relays have shown …

We consider a two‐user spectrum sharing cognitive radio multiple access channel (CR‐
MAC) coexisting with a pair of primary users (PUs). Different from the existing works in CR …

This paper considers a multiuser multichannel simultaneous wireless information and power
transfer (SWIPT) cognitive radio (CR) network, where a set of secondary users (SUs) …
