NOMA with Constellation Rotation Demo presented at INFOCOM 2020

The paper “Prototyping NOMA Constellation Rotation in Wi-Fi” by Evgeny Khorov, Aleksey Kureev, Ilya Levitsky, and Ian F. Akyildiz is published in the IEEE International Conference on Computer Communications (INFOCOM) 2020, a top-ranked conference on networking in the research community.

The paper describes a method to make an already known feature of non-orthogonal multiple access (NOMA), constellation rotation, serve for novel purpose – phase noise combating. The authors have adapted their previous experimental prototype to realize the proposed method in hardware. The renewed prototype helped to reveal the practical profit of constellation rotation in NOMA.

In 2020, INFOCOM included a main technical program, several workshops, a keynote speech, panels, and demo/poster sessions.  Due to the COVID-19 pandemic, the INFOCOM conference, including the demo session, went online. The WNL team has prepared a video for online presentation, explaining the new NOMA prototype operation and demonstrating the benefit of the innovations.

Wireless Networks Lab is a ‘Megagrant’ lab established in 2017 around the project on Cloudified Wireless Networks for 5G and beyond, led by Prof. Ian F. Akyildiz. The team regularly reports at leading IEEE conferences, runs industrial projects, and contributes to the standardization of wireless networks.
