What Role Do Intelligent Reflecting Surfaces Play in Multi-Antenna Non-Orthogonal Multiple Access?
Arthur Sousa de Sena,Dick Carrillo,Fang Fang,Pedro H. J. Nardelli,Daniel Benevides da Costa,Ugo Silva Dias,Zhiguo Ding,Constantinos B. Papadias,Walid Saad +8 more
TL;DR: This article demonstrates the main roles of IRSs in MIMO-NOMA systems and identifies key challenges and performs a comprehensive discussion of the main performance gains that can be achieved in IRS-assisted massive MIMo-NomA (IRS- NOMA) networks.
Proceedings ArticleDOI
Rural area deployment of internet of things connectivity: LTE and LoRaWAN case study
Dick Carrillo,Jorge Seki +1 more
TL;DR: Two study cases that optimize coverage and low energy consumption joining LTE and LoRaWAN wireless access technologies are proposed that are based on an element called Intelligent Terminal (IT), which is a gateway that is composed by LTE andLoRaWan interfaces.
Journal ArticleDOI
Energy Internet via Packetized Management: Enabling Technologies and Deployment Challenges
Pedro H. J. Nardelli,Hirley Alves,Antti Pinomaa,Sohail Wahid,Mauricio de Castro Tomé,Antti Kosonen,Florian Kühnlenz,Ari Pouttu,Dick Carrillo +8 more
TL;DR: It is assessed how machine-type wireless communications, as part of 5G and beyond systems, will achieve the low latency and ultra-reliability needed by the micro-grid protection while providing the massive coverage needed byThe packetized management of non-industrial loads.
Journal ArticleDOI
Event Detection System Based on User Behavior Changes in Online Social Networks: Case of the COVID-19 Pandemic
Renata Lopes Rosa,Marielle Jordane De Silva,Douglas Henrique Silva,Muhammad Ayub,Dick Carrillo,Pedro H. J. Nardelli,Demostenes Zegarra Rodriguez +6 more
TL;DR: This work aims to propose an event detection system at the early stages of an event based on changes in the users’ behavior in an OSN, which was able to detect an event almost three days earlier than the other methods.
