The Application of MIMO to Non-Orthogonal Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2015 This paper considers the application of multiple-input multiple-output (MIMO) techniques to non-orthogonal multiple access (NOMA) systems. A new design of precoding and detection matrices for MIMO-NOMA is proposed and its performance is analyzed for the ...

CSNOMA: Carrier Sense Non-Orthogonal Multiple Access [PDF]
Sensors, 2020 In this paper, we investigate the possibility of the cross-layer design of a distributed random access scheme with considering physical (PHY) and multiple access control (MAC) layers, which utilizes the interference cancellation technique. In this regard,

Cooperative Non-Orthogonal Multiple Access in 5G Systems [PDF]
IEEE Communications Letters, 2015 Non-orthogonal multiple access (NOMA) has recently received considerable attention as a promising candidate for 5G systems. A key feature of NOMA is that users with better channel conditions have prior information about the messages of the other users ...

Dynamic User Clustering and Power Allocation for Uplink and Downlink Non-Orthogonal Multiple Access (NOMA) Systems [PDF]
IEEE Access, 2016 Non-orthogonal multiple access (NOMA) has recently been considered as a key enabling technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences, multiple users are multiplexed into transmission power domain and then non ...

Non-Orthogonal Multiple Access for FSO Backhauling [PDF]
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2017 We consider a free space optical (FSO) backhauling system which consists of two base stations (BSs) and one central unit (CU). We propose to employ non-orthogonal multiple access (NOMA) for FSO backhauling where both BSs transmit at the same time and in ...
