Wireless-powered relaying based on backscatter communication has emerged as a viable
solution to extend the transmission range of energy-constrained nodes with improved power …

Wireless-powered relaying with backscatter assistance is a promising technique to increase
the coverage of self-sustainable energy-constrained devices with improved energy …

In a conventional Cooperative Non Orthogonal Multiple Access (NOMA) scheme, only one
user from the NOMA pair acts as a relay and forwards information to the other user. In this …

We propose a spectral-efficient coordinated direct and relayed transmission (CDRT) scheme
for a relay-assisted downlink system with a near user and a far user. The proposed scheme …

In this paper, a backscatter cooperation (BC) scheme is proposed for non-orthogonal
multiple access (NOMA) downlink transmission. The key idea is to backscatter the surplus …

Non‐orthogonal multiple access (NOMA) and ambient backscatter communication are two
promising techniques recommended for the fifth generation wireless network. This work …

In this paper, we focus on the issue how to reduce the throughput performance gap between
a cell-center user and a cell-edge user in a two-user downlink non-orthogonal multiple …

In this paper, an energy harvesting enabled cooperative non-orthogonal multiple access
(NOMA) system for a multi-cell network is investigated. Particularly, during the direct …

We study a downlink non-orthogonal multiple access (NOMA) system, in which a base
station (BS) serves a near user and a far user on the same frequency band simultaneously …

Backscatter communication and non-orthogonal multiple access (NOMA) are emerging
paradigms in wireless communication that offer promising solutions to enhance the spectral …
