Coordinated Pilot Transmissions for Detecting the Signal Sparsity Level in a Massive IoT Network under Rayleigh Fading
Onel L. A. López, Glauber Brante, Richard D. Souza +2
Grant-free protocols exploiting compressed sensing (CS) multi-user detection (MUD) are appealing for solving the random access problem in massive machine-type communications (mMTC)…
Exploring the Non-Overlapping Visibility Regions in XL-MIMO Random Access Protocol
José Carlos Marinello Filho, Glauber Brante, Richard Demo Souza +1
The recent extra-large scale massive multiple-input multiple-output (XL-MIMO) systems are seen as a promising technology for providing very high data rates in increased user-densit…
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…
Employing Antenna Selection to Improve Energy-Efficiency in Massive MIMO Systems
Masoud Arash, Ehsan Yazdian, Mohammad sadegh Fazel +2
Massive MIMO systems promise high data rates by employing large number of antennas, which also increases the power usage of the system as a consequence. This creates an optimizatio…
On the Performance of Secure Full-Duplex Relaying under Composite Fading Channels
Hirley Alves, Glauber Brante, Richard D. Souza +2
We assume a full-duplex (FD) cooperative network subject to hostile attacks and undergoing composite fading channels. We focus on two scenarios: \textit{a)} the transmitter has ful…
