The non-orthogonal multiple access (NOMA) system is considered an important technology
that enables the fifth-generation (5G) wireless systems and beyond to satisfy different …

In this work, we propose globally optimal power allocation strategies to maximize the users
sum-rate (SR), and system energy efficiency (EE) in the downlink of single-cell multicarrier …

This paper considers a cooperative device-to-device (D2D) system with non-orthogonal
multiple access (NOMA). We assume that the base station (BS) can simultaneously …

In this paper, we proposed a joint user pairing (UP) and power allocation (PA) algorithm in
the non-orthogonal multiple access uplink communication systems, aiming at improving the …

Non-orthogonal multiple access (NOMA)-based cognitive wireless networks can improve the
spectral efficiency to utilize the vacant spectrum resource and exploit the power domain …

The densification of mobile networks should enable the fifth generation (5G) mobile
networks to cope with the ever increasing demand for higher rate traffic, reduced latency …

In this paper, we investigate the spectrum resource and power allocation problem for the
tradeoff between maximizing the sum rate and minimum rate requirements of users in non …

We propose a tractable expression for the outage probability in single-cell uplink non-
orthogonal multiple access (NOMA) systems serving an arbitrary number of users. The …

Light-emitting diode (LED)-based visible light communication (VLC) is a great promising
high-speed wireless access solution due to its low power consumption, no electromagnetic …

The number of Internet of Things (IoT) applications and devices has been continuously
increasing and is expected to continue to do so in the upcoming years. In this context, we …
