In Cognitive Radio Non-Orthogonal Multiple Access (CR-NOMA), hybrid successive
interference cancellation (SIC) was proposed to improve the probability for a secondary user …

With the development of low-cost computer chips and wireless networks, any object or thing
can become a component of the Internet of Things (IoT). As a result, these disparate things …

An active reconfigurable intelligent surface (RIS)-aided multi-user downlink communication
system is investigated, where non-orthogonal multiple access (NOMA) is employed to …

In this paper overview of recent selected works that deal with novel directions in which Non
orthogonal multiple access (NOMA) research is progressing is presented. These include the …

In large-scale wireless sensor networks (WSNs), spectrum efficiency and energy
consumption are two challengeable problems to be solved due to the increasing traffic …

This correspondence investigates a joint power control, channel selection, and user
dynamic access scheme to maximize the sum rate of non-orthogonal multiple access …

In this paper, we consider a downlink non-orthogonal multiple access (NOMA) system over
Nakagami-m channels. The single-antenna base station serves two single-antenna NOMA …

The demand for bandwidth-intensive and delay-sensitive services is surging daily with the
development of 5G technology, resulting in fierce competition for scarce radio resources …

This research presents a unified performance analysis methodology for the power domains
