A New Green Prospective of Non-orthogonal Multiple Access (NOMA) for 5G [PDF]
Information, 2020 Energy efficiency is a major concern in the emerging mobile cellular wireless networks since massive connectivity is to be expected with high energy requirements from the network operators. Non-orthogonal multiple access (NOMA) being the frontier multiple access scheme for 5G, there exists numerous research attempts on enhancing the energy efficiency ...

Partial Non-Orthogonal Multiple Access (NOMA) in Downlink Poisson Networks [PDF]
IEEE Transactions on Wireless Communications, 2020 Non-orthogonal multiple access (NOMA) allows users sharing a resource-block to efficiently reuse spectrum and improve cell sum rate $\mathcal{R}_{\rm tot}$ at the expense of increased interference. Orthogonal multiple access (OMA), on the other hand, guarantees higher coverage.
