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

Nonorthogonal multiple access (NOMA), which can improve the spectrum efficiency and
system throughput compared with conventional orthogonal multiple access (OMA), has been …

We investigate the system performance of a nonorthogonal multiple access (NOMA) based
downlink amplify-and-forward relay network over Nakagami-fading channels with imperfect …

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 …

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 …

Non-orthogonal multiple access (NOMA) is a promising technique for the fifth generation
(5G) wireless communications. As users with good channel conditions can serve as relays to …

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 …

Non-orthogonal multiple access (NOMA) is regarded as a candidate radio access technique
for the next generation wireless networks because of its manifold spectral gains. A two …

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 …
