In this paper, an uplink scheme that exploits cooperative diversity using power domain
nonorthogonal multiple access (NOMA), termed UCD‐NOMA, with successive interference …

Non‐orthogonal multiple access (NOMA), an emerging technology to improve system
capacity and spectrum efficiency, has attracted significant attention. In this study, the authors …

This letter presents a new downlink cooperative non-orthogonal multiple access (NOMA)
transmission scheme to serve three users within only two time slots. The scheme involves a …

This paper has investigated a downlink non-orthogonal multiple access (NOMA) cooperative
scheme with user-assisted relaying, where near users are viewed as decode-and-forward …

Non-orthogonal multiple access (NOMA) has attracted a significant attention to the research
community as a potential candidate for 5G or future radio access. This article presents a …

In this paper, a new transmit diversity scheme is proposed for cooperative pseudo-non-
orthogonal multiple access (Pseudo-NOMA) without assuming full channel state information …

Nonorthogonal multiple access (NOMA) has been regarded as an appropriate multiple‐
access technique for fifth generation due to its radio‐frequency spectrum effective usage …

A coordinated direct and relay transmission is proposed using uplink non-orthogonal
multiple access (UP-NOMA). A two-user UP-NOMA scenario is considered, where a cell …

This study investigates a cooperative user relaying non-orthogonal multiple access (NOMA),
in which the near user (NU) works as a relay for the far user (FU) to convey data from the …

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 …
