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) technique is an expert on channel differences
exploiting. In this paper, a dual-hop NOMA-based cooperative relaying network where a …

In this study, non‐orthogonal multiple access (NOMA)‐based coordinated direct and relay
transmission (CDRT) is considered, where a base station (BS) directly communicates with …

A two-way relay non-orthogonal multiple access (TWR-NOMA) system is investigated, where
two groups of NOMA users exchange messages with the aid of one half-duplex decode-and …

Power allocation plays an important role in cooperative non-orthogonal multiple access
(NOMA) systems. To guarantee the quality of service (QoS) requirements of users, we …

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 …

A Co-operative user Relaying Full Duplex Non Orthogonal Multiple Access (CR-FD-NOMA)
system is considered, when there is no direct link between base station and the far user …

In this paper, we investigate a non-orthogonal multiple access (NOMA) assisted multi-
antenna two-way relay system, where multi-antenna users apply NOMA to support …

Non-orthogonal multiple access (NOMA) is a promising multiple access technique, which
exploits the power domain to enhance the spectral efficiency of the fifth generation (5G) …

This paper studies the application of simultaneous wireless information and power transfer
(SWIPT) to downlink non-orthogonal multiple access (NOMA) system. A novel cooperative …
