Towards 6G MIMO: Massive Spatial Multiplexing, Dense Arrays, and Interplay Between Electromagnetics and Processing
Emil Björnson, Chan-Byoung Chae, Robert W. Heath +7
The increasing demand for wireless data transfer has been the driving force behind the widespread adoption of Massive MIMO (multiple-input multiple-output) technology in 5G. The ne…
Optimal Dual-Polarized Planar Arrays for Massive Capacity Over Point-to-Point MIMO Channels
Amna Irshad, Alva Kosasih, Emil Björnson +1
Future wireless networks must provide ever higher data rates. The available bandwidth increases roughly linearly as we increase the carrier frequency, but the range shrinks drastic…
Holographic MIMO Communications: What is the benefit of closely spaced antennas?
Antonio Alberto D'Amico, Luca Sanguinetti
Holographic MIMO refers to a (possibly large) array with a large number of individually controlled and densely deployed antennas. The objective of this paper is to provide further…
DFT-Based Channel Estimation for Holographic MIMO
Antonio Alberto D'Amico, Giacomo Bacci, Luca Sanguinetti
Holographic MIMO (hMIMO) systems with a massive number of individually controlled antennas N make minimum mean square error (MMSE) channel estimation particularly challenging, due…
Impact of Phase Noise on Uplink Cell-Free Massive MIMO OFDM
Yibo Wu, Luca Sanguinetti, Ulf Gustavsson +2
Cell-Free massive MIMO networks provide huge power gains and resolve inter-cell interference by coherent processing over a massive number of distributed instead of co-located anten…
Spherical Wavefronts Improve MU-MIMO Spectral Efficiency When Using Electrically Large Arrays
Giacomo Bacci, Luca Sanguinetti, Emil Björnson
Modern MIMO communication systems are almost exclusively designed under the assumption of locally plane wavefronts over antenna arrays. This is known as the far-field approximation…
