In this paper, we study the performance of a cooperative non‐orthogonal multiple access (NOMA) system with a dedicated relay. This relay is full duplex (FD) and works in an amplify …
In this paper, we study the performance improvement methods for a cell-edge user of two- user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end …

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 …
JB Kim, IH Lee - IEEE Communications Letters, 2015 - ieeexplore.ieee.org
In this work, non-orthogonal multiple access (NOMA) in coordinated direct and relay transmission (CDRT) is introduced, where a base station (BS) directly communicates with …
In this paper, a novel cooperative non-orthogonal multiple access (NOMA) system is proposed, where one near user is employed as decode-and-forward relaying switching …
Y Xu, G Wang, L Zheng, S Jia - IET Communications, 2018 - Wiley Online Library
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 …
M Yang, J Chen, L Yang, L Lv, B He, B Liu - IEEE Access, 2019 - ieeexplore.ieee.org
This paper studies the coordinated direct and relay transmission (CDRT) in the non- orthogonal multiple access network, which consists of a base station (BS), a cell-center user …
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 …
