Baseband-Free Wideband MU-MIMO OFDM via Stacked Intelligent Metasurfaces

Zheao Li, Jiancheng An, Chau Yuen

This paper proposes a novel baseband-free wideband MU-MIMO OFDM transmitter architecture enabled by two cascaded stacked intelligent metasurfaces (SIMs). Unlike conventional wireless transmitters, the proposed design shifts symbol loading, MU-MIMO precoding, and OFDM modulation f…Read more
