In this study, we explore a hybrid non-orthogonal multiple access and time division multiple
access (NOMA-TDMA) approach designed to maximize sum throughput in a wireless …

Power domain non-orthogonal multiple access (PD-NOMA) has been widely recognized a
spectrum-efficient multi-user transmission method when the channel gains across different …

The rapid evolution of wireless communication has affected unmanned aerial vehicles
(UAV), which are expected to be used in diverse applications in smart cities, military …

Many Internet of Things (IoT) networks with Radio Frequency (RF) powered devices operate
over a shared medium. They thus require a channel access protocol. Unlike conventional …

The recent development of the Internet of Things (IoT) devices offers an intelligent concept
for integrating massive number of interconnected wireless devices. However, supporting …

This paper investigates a secrecy energy efficiency (SEE) optimization problem for a
multiple-input multiple-output non-orthogonal multiple access network. In particular, a multi …

Non-orthogonal multiple access (NOMA) is a promising and key wireless technology for the
next generation of mobile communications. Considering that spectral efficiency (SE) and …

The capacity restriction that the other conventional orthogonal multiple access (OMA)
methods encounter can be overcome by non-orthogonal multiple access (NOMA) …

Recently, several multiple access (MA) have been proposed to support the massive
connectivity of the cognitive radio (CR) internet-of-things IoT-based networks. Among these …

This work proposes a cooperative NOMA system that operates on the time-sharing model,
namely TS-C-NOMA. According to this paradigm, a base station provides direct service to a …
