Optimum power allocation for non-orthogonal multiple access (NOMA)
2016 IEEE 10th International Conference on Application of Information and Communication Technologies (AICT), 2016An optimum power allocation scheme for non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC) technique for downlink channels of next generation cellular networks is proposed in this paper. In NOMA downlinks, the signals for each user are superimposed at the transmitter side and SIC is implemented at the receiver side to ...

Coordinated Non-Orthogonal Multiple Access (CO-NOMA)
2016 IEEE Global Communications Conference (GLOBECOM), 2016We 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 ...

Performance of Non-Orthogonal Multiple Access (NOMA) in a C-RAN System
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017Cloud radio access network(C-RAN) has been proposed as a novel mobile network architecture allowing centralized processing. Resource allocation (RA) is the core task in order to coordinate transmissions.In this paper efficient resource allocation technique in non-orthogonal multiple access (NOMA) based C-RAN systems is proposed. The task of RA is solved

A Novel Interference Cancellation Technique for Non-Orthogonal Multiple Access (NOMA)
2015 IEEE Global Communications Conference (GLOBECOM), 2014In this paper, a novel interference cancellation (IC) technique is proposed for asynchronous non-orthogonal multiple access (NOMA) systems. The bit error rate (BER) performance of an uplink NOMA system with the proposed IC technique is presented.

SGMA: Semi-granted multiple access for non-orthogonal multiple access (NOMA) in 5G networking
Journal of Network and Computer Applications, 2018Abstract With the rapid prosperity of mobile Internet, proliferating smart terminals, and deep penetration of Internet of things (IoTs), the fourth generation mobile communication system (4G) has become increasingly unable to meet the human needs. Therefore, the fifth generation mobile communication system (5G), being studied world-widely, needs to ...

Cooperative Relaying Based Non-Orthogonal Multiple Access (NOMA) With Relay Selection
IEEE Transactions on Vehicular Technology, 2018In this paper, we propose a two-phase non-orthogonal multiple access (NOMA) scheme with cooperative relaying. In the first phase, an access point (AP) linearly combines the signals of near-user $\mathrm U_1$ and far-user $\mathrm U_2$ and then broadcasts

As a promising downlink multiple access scheme for future radio access (FRA), this paper discusses the concept and practical considerations of non-orthogonal multiple access (NOMA) with a successive interference canceller (SIC) at the receiver side. The goal is to clarify the benefits of NOMA over orthogonal multiple access (OMA) such as OFDMA adopted ...
