Non-Orthogonal Multiple Access

Advanced Computing and Communications, 2019
Non-orthogonal multiple access (NOMA) has been recently proposed as a technique to increase the network throughput and to support massive connectivity, which are major requirements in the fifth generation (5G) communication systems. The NOMA can be realized through two different approaches, namely, in (a) power-domain, and (b) code-domain. In the power-

Full-Duplex Non-Orthogonal Multiple Access Networks

2018
Full-duplex (FD) has the potential to double the resource utilization of cellular networks by enabling simultaneous transmissions in the uplink (UL) and downlink (DL) directions using the same time and frequency resource. Several challenges arise from integrating FD with non-orthogonal multiple access (NOMA) networks.

Coordinated Non-Orthogonal Multiple Access (CO-NOMA)

2016 IEEE Global Communications Conference (GLOBECOM), 2016
We propose a Coordinated Non-Orthogonal Multiple Access (CO-NOMA) scheme for resource allocation in the context of mobile networks. NOMA refers to schemes where multiple users can access the wireless channel in the same frequency band simultaneously. In this study, we consider NOMA with power domain multiplexing, where the near- far property in space ...

5G‐oriented non‐orthogonal multiple access technology

International Journal of Communication Systems, 2020
SummaryWith the changes of the times and the rapid development of the mobile Internet and the Internet of Things, network communications are facing increasingly severe challenges. Due to the user exclusivity of the orthogonal resources of the existing orthogonal multiple access technology, it is difficult for the number of accessible users and the ...

Bidirectional relaying using non-orthogonal multiple access

Physical Communication, 2019
Abstract A half-duplex bidirectional relaying (BR) technique using non-orthogonal multiple access (NOMA) (termed as BR-NOMA) is proposed and investigated in this paper. In BR-NOMA, multiple users in one NOMA group can exchange information simultaneously with multiple users in another NOMA group through a common relay.

Experimental Trials on Non-Orthogonal Multiple Access

2018
Non-orthogonal multiple access (NOMA) is a novel multi-user multiplexing scheme, which overlaps the radio resources of multiple users in an non-orthogonal manner in order to improve spectral efficiency. NOMA is able to contribute to the improvement of the trade-off between system capacity and user fairness by assigning different power ratios to the ...
