This paper studies the problem of joint relay selection and power allocation (J-RS-PA) for
non-orthogonal multiple-access (NOMA)-based multicast cognitive radio networks with …

The Secondary Users (SUs) in cognitive radio networks, are required to perform
transmissions such that they do not interfere with the Primary User's (PU) transmission. This …

The L-band digital aeronautical communications system (LDACS) is a cellular air-ground
data link for air traffic control. It is a cornerstone of the future aeronautical communications …

Cognitive relay network is a spectrum dynamic paradigm that exploits the unused portions of
the licensed spectrum. This is based on merging both cooperative relaying techniques and …

The radio spectrum is witnessing a major paradigm shift from fixed spectrum assignment
policy to the dynamic spectrum access, which will completely change the way radio …

Abstract Cooperative Spectrum Sharing (CSS) is a Dynamic Spectrum Access mechanism
aimed at providing incentives for both primary users (PUs) and secondary users (SUs) …

Cognitive radio networks (CRNs) implementing spectrum sharing between primary and
secondary users are able to provide a needed solution for the increasing spectrum scarcity …

Cognitive radio networks (CRNs) can improve spectrum utilization by allowing secondary
users (SUs) to dynamically access channels unoccupied by primary users (PUs). The …

Spectral efficiency in cognitive radio network (CRN) can be achieved by allowing unlicensed
users or secondary users (SUs) to coexist with legacy spectrum holders or primary users …

The spectrum frequency in the wireless communication industry is getting great attention
due to the internet of things (IoT) technology's growth. However, the radio spectrum's …
