A tutorial on cooperative non-orthogonal multiple access networks
The Journal of Defence Modeling and Simulation: Applications, Methodology, Technology, 2021In this paper, we explore the possibilities and advantages of cooperative relaying with the addition of non-orthogonal multiple access (NOMA). First, the possibilities of NOMA for fifth-generation (5G) and beyond networks is discussed followed by the ...

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 ...

Non-Orthogonal Multiple Access
Advanced Computing and Communications, 2019Non-orthogonal multiple access (NOMA) has been recently proposed as a technique to increase the network throughput and to support massive connectivity, which are major requirements in the fifth generation (5G) communication systems. The NOMA can be realized through two different approaches, namely, in (a) power-domain, and (b) code-domain. In the power-

Non-Orthogonal Multiple Access for Multiple-Antenna Relaying Networks
IEEE Communications Letters, 2015In this letter, we design non-orthogonal multiple access (NOMA) for multiple-antenna relaying networks. The receive antennas at the mobile users are assumed to adopt maximal ratio combining (MRC), whereas the transmit antenna that maximizes the instantaneous signal-to-noise ratio (SNR) at the relay is selected.
