This paper investigates an amplify-and-forward (AF) relaying assisted non-orthogonal
multiple access (NOMA) system over Nakagami-m fading channels, where both imperfect …

Non-orthogonal multiple access (NOMA) has been conceived as a breakthrough technology
for the fifth generation (5G) wireless networks. With imperfect channel state information …

This paper investigates a multi-hop decode-and-forward (DF) relay-aided non-orthogonal
multiple access (MH-DF-R-NOMA) scheme. The model overcomes the problems associated …

In this study, non‐orthogonal multiple access (NOMA)‐based multiple‐antenna and multiple‐
relay networks over Nakagami‐m fading channels with imperfect channel state information …

In this paper, we investigate a downlink cooperative non-orthogonal multiple access
(NOMA) network with decode-and-forward relaying, where two scenarios of user relaying …

Although the theory of nonorthogonal multiple access (NOMA) has been widely investigated,
so far, there is a lack of applying beamforming into NOMA systems. In this article, we …

This paper studies the application of cooperative techniques for non-orthogonal multiple
access (NOMA). More particularly, the fixed gain amplify-and-forward (AF) relaying with …

Abstract In fifth-generation (5G) wireless communication systems, non-orthogonal multiple
access (NOMA) has been considered as a promising multiple access technique. In this …

A Co-operative user Relaying Full Duplex Non Orthogonal Multiple Access (CR-FD-NOMA)
system is considered, when there is no direct link between base station and the far user …

A cooperative relaying system based on non-orthogonal multiple access (NOMA) is
considered a promising technique in next-generation wireless communications. In this letter …
