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 ...

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 ...

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.

IoT-Based Coordinated Direct and Relay Transmission With Non-Orthogonal Multiple Access
IEEE Wireless Communications Letters, 2021This letter studies an Internet-of-Things (IoT)-based coordinated direct and relay transmission (CDRT) adopting non-orthogonal multiple access (NOMA), where an information source directly communicates with a strong user while a weak user needs the help ...
