Abstract

nonlinear processing

non-orthogonal transmission

massive connectivity

This demo showcases how nonlinear processing can enable massive, scalable connectivity, demonstrating that even with a single antenna access point, we can support multiple concurrently transmitted information streams at the same time-frequency resources.
