Adaptive Resource Allocation Based on Factor Graphs in Non-Orthogonal Multiple Access [PDF]
, 2022 In this paper, we propose a non-orthogonal multiple access with adaptive resource allocation. The proposed non-orthogonal multiple access assigns multiple frequency resources for each device to send packets.

Optimizing Non-Orthogonal Multiple Access in Random Access Networks [PDF]
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 Non-orthogonal multiple access (NOMA) has been considered as a promising solution for improving the spectrum efficiency of next-generation wireless networks. In this paper, the performance of a p-persistent slotted ALOHA system in support of NOMA transmissions is investigated.

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]
, 2009 At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

A Unified Framework for Non-Orthogonal Multiple Access [PDF]
IEEE Transactions on Communications, 2018 This paper proposes a unified framework of non-orthogonal multiple access (NOMA) networks. Stochastic geometry is employed to model the locations of spatially NOMA users. The proposed unified NOMA framework is capable of being applied to both code-domain NOMA (CD-NOMA) and power-domain NOMA (PD-NOMA).
