Impact of User Pairing on 5G Nonorthogonal Multiple-Access Downlink Transmissions

IEEE Transactions on Vehicular Technology, 2016
Nonorthogonal multiple access (NOMA) represents a paradigm shift from conventional orthogonal multiple-access (MA) concepts and has been recognized as one of the key enabling technologies for fifth-generation mobile networks. In this paper, the impact of

To pair or not to pair? [PDF]

open access: possibleNature Physics, 2010
Is the mysterious pseudogap in the copper oxide superconductors a signature of preformed pairs or a competing ordered state? Measurements of broken symmetries suggest that the pseudogap cannot originate from superconductivity alone.

Optimal User Pairing for Downlink Non-Orthogonal Multiple Access (NOMA)

IEEE Wireless Communications Letters, 2019
In 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 ...

Ising pairing in superconducting NbSe2 atomic layers

Nature Physics, 2015
The superconducting properties of NbSe2 as it approaches the monolayer limit are investigated by means of magnetotransport measurements, uncovering evidence of spin–momentum locking.

On User Pairing in Uplink NOMA

IEEE Transactions on Wireless Communications, 2018
User pairing in non-orthogonal multiple-access (NOMA) uplink is investigated considering some predefined power allocation schemes. The base station divides the set of users into disjunct pairs and assigns the available resources to these pairs.

To pair or not to pair: chromosome pairing and evolution

Current Opinion in Plant Biology, 1998
Chromosome pairing in wild-type wheat closely resembles the process in both yeast and Drosophila. The recent characterisation of a mutant Ph1 wheat and the observation that chromosome pairing in the absence of Ph1 more closely resembles that of mammals and maize has shed light on the evolution of chromosome pairing in the cereals.
