Energy Beamforming for RF Wireless Power Transfer with Dynamic Metasurface Antennas
Amirhossein Azarbahram, Onel L. A. Lopez, Richard D. Souza +2
Radio frequency (RF) wireless power transfer (WPT) is a promising technology for charging the Internet of Things. Practical RF-WPT systems usually require energy beamforming (EB),…
Age-of-Information Dependent Random Access in NOMA-Aided Multiple-Relay Slotted ALOHA
Gabriel Germino Martins de Jesus, João Luiz Rebelatto, Richard Demo Souza +1
We propose and evaluate the performance of a Non-Orthogonal Multiple Access (NOMA) dual-hop multiple relay (MR) network from an information freshness perspective using the Age of I…
Performance Analysis of Centralized and Distributed Massive MIMO for MTC
Eduardo Noboro Tominaga, Onel Luiz Alcaraz López, Hirley Alves +2
Massive Multiple-Input Multiple-Output (mMIMO) is one of the essential technologies introduced by the Fifth Generation (5G) of wireless communication systems. However, although mMI…
Performance Analysis of ML-based MTC Traffic Pattern Predictors
David E. Ruiz-Guirola, Onel L. A. Lopez, Samuel Montejo-Sanchez +2
Prolonging the lifetime of massive machine-type communication (MTC) networks is key to realizing a sustainable digitized society. Great energy savings can be achieved by accurately…
