Multi-User MIMO Enhancement using Metasurface Wavefront Bending (MWB)
Xiaolu Yang, Oscar Cespedes Vicente, Christophe Caloz
This paper introduces metasurface wavefront bending (MWB) to enhance spatial multiplexing in radiative nearfield multi-user multiple-input multiple-output (MU-MIMO) systems. By inc…
MIMO Capacity Enhancement by Grating Walls: A Physics-Based Proof of Principle
Xiaolu Yang, Oscar Cespedes Vicente, Christophe Caloz
The paper demonstrates how coating indoor walls with binary gratings can passively boost MIMO spectral efficiency by enriching non‑line‑of‑sight multipath and reducing channel corr…
Analog OFDM based on Real-Time Fourier Transformation
Xiaolu Yang, Oscar Céspedes Vicente, Christophe Caloz
This paper proposes an analog orthogonal frequency division multiplexing (OFDM) architecture based on the real-time Fourier transform (RTFT). The core enabling component is a linea…
