In this paper, we design and investigate a novel uplink/downlink (UL/DL) non-orthogonal
multiple access (NOMA) network using a common relay. Instead of successive interference …

In this correspondence, an uplink nonorthogonal multiple access (NOMA) system where the
base station (BS) trends to decode the independent information of users occupying the …

Instead of successive interference cancellation (SIC) for uplink non-orthogonal multiple
access systems with fixed decoding order based on the statistical channel state information …

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 …

In this paper, antenna diversity is used to improve the outage performance of downlink non-
orthogonal multiple access (NOMA) systems combined with single-user multiple-input …

Non-orthogonal multiple access (NOMA) is a promising technology to increase system
throughput and accommodate massive connectivity via non-orthogonal resource allocation …

Conventional non-orthogonal multiple access (NOMA) schemes assume perfect channel
state information (CSI) at the transmitter side, which is nearly impractical for many …

In fifth-generation wireless communication networks, Non-Orthogonal Multiple Access
(NOMA) has attracted much attention in both academic and industrial fields because of its …

We propose an optimal joint user association and decoding order selection scheme for
distributed uplink non-orthogonal multiple access (DU-NOMA) with fixed transmission rates …

Non-orthogonal multiple access (NOMA) is a favourable technique for future wireless
networks to meet massive connectivity and high throughput. The primary concept of NOMA …
