Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

Cognitive radio is a promising technology that enables an unlicensed user (also known as a
cognitive user) to identify the white space of a licensed spectrum band (called a spectrum …

Spectrum sensing is the prerequisite of opportunistic spectrum access in cognitive sensor
networks (CSNs) as its reliability determines the success of transmission. However …

This article explores cooperative communications for drone swarms which become an
essential part of space-air-ground integrated networks (SAGINs), since drones (also called …

In this paper, we address the challenging and important cooperative spectrum sensing
(CSS) problem with M-ary quantized data under spectrum sensing data falsification (SSDF) …

Cooperative Cognitive Radio Networks: The Complete Spectrum Cycle provides a solid
understanding of the foundations of cognitive radio technology, from spectrum sensing …

In this paper, we consider a decode-and-forward (DF) cooperation system consisting of two
cooperative users in sending their information to a common destination, for which the …

Cognitive radio is an enabling technology to solve the spectrum scarcity problem in wireless
communication. This is based on the concept of opportunistic spectrum access. Spectrum …

In this correspondence, we investigate a selective relay spectrum sensing and best relay
data transmission (SRSS-BRDT) scheme for multiple-relay cognitive radio networks …

In cognitive radio (CR) networks, cooperative spectrum sensing is utilized to improve the
sensing performance to avoid potential interference to primary users (PUs) and increase …
