Reinforcenment Learning-Aided NOMA Random Access: An AoI-Based Timeliness Perspective
Felippe Moraes Pereira, Jamil de Araujo Farhat, João Luiz Rebelatto +2
In this paper, we investigate the age-of-information (AoI) of a power domain non-orthogonal multiple access (NOMA) network, where multiple internet-of-things (IoT) devices transmit…
Probabilistic Allocation of Payload Code Rate and Header Copies in LR-FHSS Networks
Jamil de Araujo Farhat, Jean Michel de Souza Sant'Ana, João Luiz Rebelatto +3
We evaluate the performance of the LoRaWAN Long-Range Frequency Hopping Spread Spectrum (LR-FHSS) technique using a device-level probabilistic strategy for code rate and header rep…
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…
Network-Coded Cooperative LoRa Network with D2D Communication
L. H. O. Alves, J. L. Rebelatto, R. D. Souza +1
We evaluate the outage probability and the energy efficiency (EE) of a LoRa network when the end-devices (EDs) are capable of exchanging messages with a device-to-device (D2D) tech…
Network Slicing for eMBB and mMTC with NOMA and Space Diversity Reception
Eduardo Noboro Tominaga, Hirley Alves, Onel Luiz Alcaraz López +3
In this work we study the coexistence in the same Radio Access Network (RAN) of two generic services present in the Fifth Generation (5G) of wireless communication systems: enhance…
Non-Orthogonal Multiple Access and Network Slicing: Scalable Coexistence of eMBB and URLLC
Eduardo Noboro Tominaga, Hirley Alves, Richard Demo Souza +2
The 5G systems will feature three generic services: enhanced Mobile BroadBand (eMBB), massive Machine-Type Communications (mMTC) and Ultra-Reliable and Low-Latency Communications (…
Maximum Secrecy Throughput of MIMOME FSO Communications with Outage Constraints
Marcos Eduardo Pivaro Monteiro, João Luiz Rebelatto, Glauber Brante +1
In this work, we consider a scenario where two multiple-aperture legitimate nodes (Alice and Bob) communicate by means of Free-Space Optical (FSO) communication in the presence of…
Comments on "Finite-SNR Diversity-Multiplexing Tradeoff for Network Coded Cooperative OFDMA Systems"
Thiago Henrique Ton, João Luiz Rebelatto, Richard Demo Souza
In the paper "Finite-SNR Diversity-Multiplexing Tradeoff for Network Coded Cooperative OFDMA Systems', the authors adopt a recently proposed subcarrier allocation algorithm aiming…
Secrecy Outage Probability of Network-Coded Cooperative Communication
João Luiz Rebelatto, Richard Demo Souza, Rodrigo Tsuneyoshi Kaido +2
We evaluate the secrecy performance of a multiple access cooperative network where the destination node is wiretapped by a malicious and passive eavesdropper. We propose the applic…
Time-Switching Uplink Network-Coded Cooperative Communication with Downlink Energy Transfer
Guilherme Luiz Moritz, João Luiz Rebelatto, Richard Demo Souza +2
In this work, we consider a multiuser cooperative wireless network where the energy-constrained sources have independent information to transmit to a common destination, which is a…
Multi-User Cooperative Diversity through Network Coding Based on Classical Coding Theory
João Luiz Rebelatto, Bartolomeu F. Uchôa-Filho, Yonghui Li +1
In this work, we propose and analyze a generalized construction of distributed network codes for a network consisting of users sending different information to a common base st…
Generalized Distributed Network Coding Based on Nonbinary Linear Block Codes for Multi-User Cooperative Communications
João Luiz Rebelatto, Bartolomeu F. Uchôa-Filho, Yonghui Li +1
In this work, we propose and analyze a generalized construction of distributed network codes for a network consisting of M users sending different information to a common base stat…
