Efficient Channel Estimation With Shorter Pilots in RIS-Aided Communications: Using Array Geometries and Interference Statistics
Özlem Tuğfe Demir, Emil Björnson, Luca Sanguinetti
Accurate estimation of the cascaded channel from a user equipment (UE) to a base station (BS) via each reconfigurable intelligent surface (RIS) element is critical to realizing the…
Uplink Cell-Free Massive MIMO OFDM with Phase Noise-Aware Channel Estimation: Separate and Shared Local Oscillators
Yibo Wu, Luca Sanguinetti, Musa Furkan Keskin +3
Cell-free massive multiple-input multiple-output (mMIMO) networks enhance coverage and spectral efficiency (SE) by distributing antennas across access points (APs) with phase coher…
Optimizing RIS Impairments through Semantic Communication
Nour Hello, Mattia Merluzzi, Emilio Calvanese Strinati +1
This paper investigates how semantic communication can effectively influence and potentially redefine the limitations imposed by physical layer settings. Reconfigurable Intelligent…
MMSE Channel Estimation in Large-Scale MIMO: Improved Robustness with Reduced Complexity
Giacomo Bacci, Antonio Alberto D'Amico, Luca Sanguinetti
Large-scale MIMO systems with a massive number N of individually controlled antennas pose significant challenges for minimum mean square error (MMSE) channel estimation, based on u…
