In this paper, a two-stage superposed transmission scheme for cooperative nonorthogonal
multiple access (NOMA) systems is proposed. During the first N time slots, the source …

Non-orthogonal multiple access (NOMA) is one of the promising radio access techniques in
5G communication networks. In this paper, a cooperative NOMA relaying scheme with two …

In this paper, an enhanced transmission scheme for cooperative relaying networks with non-
orthogonal multiple access (ECRN-NOMA) is proposed. In the proposed scheme, two …

In this paper, we study the performance of a downlink non-orthogonal multiple access-based
cooperative relay system with a single relay over Nakagami-m fading channels, where both …

Non-orthogonal multiple access (NOMA) is a promising multiple access technique for the
fifth generation (5G) wireless communications. In order to enhance the performance gains of …

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 …

In this letter, the outage performance of a satellite-assisted cooperative non-orthogonal
multiple access (NOMA) system is studied, where a terrestrial source communicates with …

This paper investigates a cooperative non-orthogonal multiple access system, in which a
base station communicates with two far users with the aid of a decode-and-forward (DF) …

Cooperative non-orthogonal multiple access (NOMA) systems inherit advantages of the
NOMA protocol and the cooperative relay. In this paper, we propose cooperative NOMA …

This letter studies the outage performance of cooperative non-orthogonal multiple access
(NOMA) network by adopting an amplify-and-forward relay. An accurate approximation for …
