Dynamic Metasurfaces for Massive MIMO Networks

Nir Shlezinger, Or Dicker, Yonina C. Eldar, Mohammadreza F. Imani, David R. Smith

ICASSP 2019accepted

Massive multiple-input multiple-output (MIMO) communications are the focus of considerable interest in recent years. While theoretical gains of such massive MIMO have been established, implementing MIMO systems with large-scale antenna arrays in practice is challenging. Among the practical difficult…
