Electromagnetic Based Communication Model for Dynamic Metasurface Antennas
Robin Jess Williams, Pablo Ramirez-Espinosa, Jide Yuan +1
Dynamic metasurface antennas (DMAs) arise as a promising technology in the field of massive multiple-input multiple-output (mMIMO) systems, offering the possibility of integrating…
Performance Evaluation of Dynamic Metasurface Antennas: Impact of Insertion Losses and Coupling
Pablo Ramírez-Espinosa, Robin Jess Williams, Jide Yuan +1
This paper evaluates the performance of multi-user massive multiple-input multiple-output (MIMO) systems in which the base station is equipped with a dynamic metasurface antenna (D…
Reconfigurable, Intelligent, and SustainableWireless Environments for 6G Smart Connectivity
Emilio Calvanese Strinati, George C. Alexandropoulos, Henk Wymeersch +7
Various visions on the forthcoming sixth Generation (6G) networks point towards flexible connect-and-compute technologies to support future innovative services and the correspondin…
A Deep Learning Approach to Location- and Orientation-aided 3D Beam Selection for mmWave Communications
Sajad Rezaie, Elisabeth de Carvalho, Carles Navarro Manchón
Position-aided beam selection methods have been shown to be an effective approach to achieve high beamforming gain while limiting the overhead and latency of initial access in mill…
Uncoordinated and Decentralized Processing in Extra-Large MIMO Arrays
Abolfazl Amiri, Carles Navarro Manch'on, Elisabeth de Carvalho
We propose a decentralized receiver for extra-large multiple-input multiple-output (XL-MIMO) arrays. Our method operates with no central processing unit (CPU) and all the signal de…
Quasi-Distributed Antenna Selection for Spectral Efficiency Maximization in Subarray Switching XL-MIMO Systems
Joao Henrique Inacio de Souza, Abolfazl Amiri, Taufik Abrao +2
In this paper, we consider the downlink (DL) of a zero-forcing (ZF) precoded extra-large scale massive MIMO (XL-MIMO) system. The base-station (BS) operates with limited number of…
