Super-Beamforming in Holographic MIMO
Andrea Pizzo, Angel Lozano
The conventional linear scaling of beamforming gain with the number of antennas is not a fundamental physical limitation, but rather a consequence of the half-wavelength spacin…
Beamforming Saturation in Two-Timescale RIS-assisted Communication
Masoud Sadeghian, Angel Lozano, Gabor Fodor
This paper considers wireless communication assisted by a reconfigurable intelligent surface (RIS), focusing on the two-timescale approach, in which the RIS phase shifts are optimi…
Evaluating the Performance of Reconfigurable Intelligent Base Stations through Ray Tracing
Sina Beyraghi, Giovanni Interdonato, Giovanni Geraci +2
Massive multiple-input multiple-output (mMIMO) is a key capacity-boosting technology in 5G wireless systems. To reduce the number of radio frequency (RF) chains needed in such syst…
Mutual Coupling in Holographic MIMO: Physical Modeling and Information-Theoretic Analysis
Andrea Pizzo, Angel Lozano
This paper presents a comprehensive framework for holographic multiantenna communication, a paradigm that integrates both wide apertures and closely spaced antennas relative to the…
RIS in Indoor Environments: Benchmarking Against Ambient Propagation
Masoud Sadeghian, Andrea Pizzo, Angel Lozano
The improvements in received signal power brought about by a reflective intelligent surface (RIS) might be overstated if background propagation mechanisms such as reflections, scat…
