CSNOMA: Carrier Sense Non-Orthogonal Multiple Access [PDF]

open access: yesSensors, 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,

A Survey of Non-Orthogonal Multiple Access for 5G [PDF]

open access: yesIEEE Communications Surveys and Tutorials, 2018
In the 5th generation (5G) of wireless communication systems, hitherto unprecedented requirements are expected to be satisfied. As one of the promising techniques of addressing these challenges, non-orthogonal multiple access (NOMA) has been actively investigated in recent years. In contrast to the family of conventional orthogonal multiple access (OMA)

Rate Compatible Modulation for Non-Orthogonal Multiple Access [PDF]

open access: yesIEEE 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 ...

The Application of MIMO to Non-Orthogonal Multiple Access [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2016
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 case with a fixed set of power allocation coefficients.

Non-Orthogonal Multiple Access: A Unified Perspective [PDF]

open access: yesIEEE Wireless Communications, 2018
Non-orthogonal multiple access (NOMA) is a promising technique for future mobile communication systems, which can approach multiuser channel capacity by sharing the same time-frequency resources with multiple users. In this article, we provide a unified framework for NOMA and review the principles of various NOMA schemes in different domains with the ...
