Optimal User Pairing for Downlink Non-Orthogonal Multiple Access (NOMA)
IEEE Wireless Communications Letters, 2019In this letter, we explore user pairing in a downlink non-orthogonal multiple access (NOMA) network. As power allocation inherently intertwines with user pairing, a joint user pairing and power allocation problem is considered to optimize the achievable sum rate (ASR) with minimum rate constraint for each user, which is a mixed integer programming ...

Downlink Non-Orthogonal Multiple Access (NOMA) Constellation Rotation
2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016The non-orthogonal multiple access (NOMA) technique or more generally the non-orthogonal principle is a crucial component for the next generation cellular system. For two-user downlink NOMA, the constellations of near and far users are superposed for transmission, and maximum likelihood (ML) or successive interference cancellation (SIC) receiver is ...

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 ...
