Multiple-Antenna-Assisted Non-Orthogonal Multiple Access [PDF]
IEEE Wireless Communications, 2018 Non-orthogonal multiple access (NOMA) is potentially capable of circumventing the limitations of the classic the orthogonal multiple access schemes, hence it has recently received significant research attention both in industry and academia. This article

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

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

Dynamic Non-Orthogonal Multiple Access and Orthogonal Multiple Access in 5G Wireless Networks
IEEE Transactions on Communications, 2019 In this paper, a novel framework for dynamic multiple access technology selection among orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) techniques is proposed. For this setup, a joint resource allocation problem is formulated in which a new set of access technology selection parameters along with power and subcarrier are ...

Covert Non-Orthogonal Multiple Access
2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020We consider hiding a covert (private) message in non-orthogonal multiple access (NOMA) systems by superimposing (embedding) it under non-covert (public) messages. We determine the total detection error probability (sum of false alarm and missed detection probability), the adversary’s optimum detection strategy that minimizes the total detection error ...

Orthogonal and Quasi-Orthogonal Tree Codes with Applications to Multiple Access
IEEE Transactions on Communications, 1979The performance of orthogonal and quasi-orthogonal tree codes is considered for incoherent and coherent systems. In addition, several alternative receiver structures using hard quantizing and "greatest-of" detection are treated. Upper bounds on error probability are derived and are used as a basis for system comparison.

Multiple Codebook-Based Non-Orthogonal Multiple Access
IEEE Wireless Communications Letters, 2020Observing that employing a single codebook (CB) per user transmission block in the conventional CB-based non-orthogonal multiple access (NOMA) schemes doesn’t exploit code and interference diversity and has limitations in some unfavorable channel conditions, this letter presents multiple CB-based NOMA (MC-NOMA) in which multiple CBs are employed by a ...
