Wireless Power Transfer (WPT) is an innovative technology employed for enhancing the
energy sustainability of wireless devices with a limited life span. The idea of integrating WPT …

This article addresses the practical aspects that may affect the performance of down-link non-
orthogonal multiple access (NOMA) systems. The system performance of two down-link …

In this paper, we examine a half‐duplex cooperative multiple‐input multiple‐output non‐
orthogonal multiple access system with imperfect channel state information (CSI) and …

In this paper, a three-dimensional geometric channel model characterized by channel gain,
angle of arrival, and departure (AoA/AoD) is used to develop a non-ideal and more realistic …

In this paper, a 5G downlink multi-antenna relay assisted non-orthogonal multiple access
(NOMA) communication system is investigated. The relay can work in half-duplex (HD) or full …

This paper analyzes the performance of maximum-ratio transmission (MRT)/maximum-ratio
combining (MRC) scheme in a dual-hop non-orthogonal multiple access (NOMA) full-duplex …

In this paper, we consider a wireless system providing power allocation fairness for grouping
users by conducting a non‐orthogonal multiple access (NOMA). In particular, a rigorous …

In this paper, secure beamforming design in cooperative cognitive radio networks for
Internet of Things (IoT) is investigated, where we maximize the secrecy sum rate for the IoT …

Nonorthogonal multiple access (NOMA) is one of the most promising multiple access
techniques in fifthgeneration and beyond (5G+). It can satisfy the increase in demands of …

This paper investigates the power minimization problem for the downlink of multi-input multi-
output non-orthogonal multiple access (MIMO-NOMA) systems. The problem aims to …
