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 ...

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 ...

Trellis-Coded Non-Orthogonal Multiple Access [PDF]
IEEE Wireless Communications Letters, 2019 In this letter, we propose a trellis-coded non-orthogonal multiple access (NOMA) scheme. The signals for different users are produced by trellis coded modulation (TCM) and then superimposed on different power levels.

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 ...

Rate Compatible Modulation for Non-Orthogonal Multiple Access [PDF]
IEEE Access, 2020 We propose a new Non-Orthogonal Multiple Access (NOMA) coding scheme based on the use of a Rate Compatible Modulation (RCM) encoder for each user. By properly designing the encoders and taking advantage of the additive nature of the Multiple Access ...

Downlink Non-Orthogonal Multiple Access with Limited Feedback
IEEE Transactions on Wireless Communications, 2017 In this paper, we analyze downlink non-orthogonal multiple access (NOMA) networks with limited feedback. Our goal is to derive appropriate transmission rates for rate adaptation and minimize outage probability of minimum rate for the constant-rate data ...

Cooperative non-orthogonal multiple access in cognitive radio [PDF]
IEEE Communications Letters, 2016 This letter studies the application of non-orthogonal multiple access to a downlink cognitive radio (termed CR-NOMA) system. A new cooperative transmission scheme is proposed aimed at exploiting the inherent spatial diversity offered by the CR-NOMA ...
