This paper studies a two-user cooperative non-orthogonal multiple access network with a
novel cooperation scheme, where the source communicates with the near user directly or …

This paper investigates reconfigurable intelligent surface (RIS)-aided cognitive non-
orthogonal multiple access (NOMA) systems, where an RIS is deployed to serve two users …

Recently, non-orthogonal multiple access (NOMA)-enabled cognitive satellite-unmanned
aerial vehicle (UAV)-terrestrial networks have attracted extensive attention for the …

Non-orthogonal multiple access (NOMA) aims to increase the spectral efficiency of fifth
generation networks by relaxing the orthogonal use of radio-resources. In this paper, a …

The demands for high spectral efficiency and massive connections led the researchers to
investigate new multiple access techniques for the future wireless networks. Non-Orthogonal …

In this paper, we consider non-orthogonal multiple access (NOMA) relaying networks, where
one base station communicates with two mobile users with the aid of multiple relays. 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 …

This letter studies the impact of relay selection (RS) on the performance of cooperative non-
orthogonal multiple access (NOMA). In particular, a two-stage RS strategy is proposed, and …

In this letter, we carry out the performance analysis of the simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS) in the hybrid automatic repeat …

Combining energy harvesting with cognitive radio and nonorthogonal multiple access
(NOMA) techniques will be a notable candidate for improving both energy and spectral …
