Accelerated Randomized Methods for Receiver Design in Extra-Large Scale MIMO Arrays
Victor Croisfelt Rodrigues, Abolfazl Amiri, Taufik Abrão +2
Massive multiple-input-multiple-output (M-MIMO) features a capability for spatial multiplexing of large number of users. This number becomes even more extreme in extra-large (XL-MI…
Multiuser MIMO with Large Intelligent Surfaces: Communication Model and Transmit Design
Robin Jess Williams, Pablo Ramírez-Espinosa, Elisabeth de Carvalho +1
This paper proposes a communication model for multiuser multiple-input multiple-output (MIMO) systems based on large intelligent surfaces (LIS), where the LIS is modeled as a colle…
Assessing Wireless Sensing Potential with Large Intelligent Surfaces
Cristian J. Vaca-Rubio, Pablo Ramirez-Espinosa, Kimmo Kansanen +3
Sensing capability is one of the most highlighted new feature of future 6G wireless networks. This paper addresses the sensing potential of Large Intelligent Surfaces (LIS) in an e…
Antenna Selection for Improving Energy Efficiency in XL-MIMO Systems
José Carlos Marinello, Taufik Abrão, Abolfazl Amiri +2
We consider the recently proposed extra-large scale massive multiple-input multiple-output (XL-MIMO) systems, with some hundreds of antennas serving a smaller number of users. Sinc…
Distributed Receivers for Extra-Large Scale MIMO Arrays: A Message Passing Approach
Abolfazl Amiri, Sajad Rezaie, Carles Navarro Manchon +1
We study the design of receivers in extra-large scale MIMO (XL-MIMO) systems, i.e. systems in which the base station is equipped with an antenna array of extremely large dimensions…
Outage Analysis of Downlink URLLC in Massive MIMO systems with Power Allocation
Alexandru-Sabin Bana, Luca Sanguinetti, Elisabeth De Carvalho +1
Massive MIMO is seen as a main enabler for low latency communications, thanks to its high spatial degrees of freedom. The channel hardening and favorable propagation properties of…
