In this paper, we investigate a coordinated direct and relay transmission for uplink (CDRT-
UL) of a cooperative non-orthogonal multiple access (NOMA) system, in which two users …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient technology to
satisfy the massive data requirement of the next-generation wireless communication …

A novel coexisting passive reconfigurable intelligent surface (RIS) and active decode-and-
forward (DF) relay assisted non-orthogonal multiple access (NOMA) transmission framework …

Non-orthogonal multiple access (NOMA) is recognized as a promising radio access
technology for next generation wireless networks. In this paper, a novel full-duplex (FD) …

In this paper, a cooperative non-orthogonal multiple access (NOMA) system is studied for
the Internet-of-Things (IoT) in which a master node intends to serve multiple client nodes …

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 …

In this article, we investigate a selective decode-and-forward (DF)-aided cooperative
nonorthogonal multiple access (NOMA) system performance in the presence of practical …

In this work, we evaluate the outage probability of a two-user network-coded cooperative
(NCC) uplink system subjected to non-orthogonal multiple access (NOMA). We consider that …

Recent studies have demonstrated the superiority of non-orthogonal multiple access
(NOMA) over orthogonal multiple access (OMA) in cooperative communication networks. In …

In this letter, we propose a two-step user-paring scheme for an orthogonal frequency-
division multiplexing (OFDM)-based cooperative non-orthogonal multiple-access (NOMA) …
