Boosting 5G on Smart Grid Communication: A Smart RAN Slicing Approach
Dick Carrillo, Charalampos Kalalas, Petra Raussi +7
Fifth-generation (5G) and beyond systems are expected to accelerate the ongoing transformation of power systems towards the smart grid. However, the inherent heterogeneity in smart…
Performance analysis of downlink MIMO-NOMA systems over Weibull fading channels
Lenin Patricio Jiménez Jiménez, Fernando Darío Almeida García, Maria Cecilia Luna Alvarado +4
This work analyzes the performance of a downlink multi-user multiple-input multiple-output (MU-MIMO) non-orthogonal multiple access (NOMA) communications system. To reduce hardware…
Doppler Estimation for High-Velocity Targets Using Subpulse Processing and the Classic Chinese Remainder Theorem
Fernando Darío Almeida García, André Saito Guerreiro, Gustavo Rodrigues de Lima Tejerina +3
In pulsed Doppler radars, the classic Chinese remainder theorem (CCRT) is a common method to resolve Doppler ambiguities caused by fast-moving targets. Another issue concerning hig…
Highly accurate closed-form approximation for the probability of detection of Weibull fluctuating targets in non-coherent detectors
Fernando Darío Almeida García, Andrea Carolina Flores Rodriguez, Gustavo Fraidenraich
In this paper, we derive a highly accurate approximation for the probability of detection (PD) of a non-coherent detector operating with Weibull fluctuation targets. To do so, we a…
Containing Future Epidemics with Trustworthy Federated Systems for Ubiquitous Warning and Response
Dick Carrillo, Lam Duc Nguyen, Pedro H. J. Nardelli +11
In this paper, we propose a global digital platform to avoid and combat epidemics by providing relevant real-time information to support selective lockdowns. It leverages the perva…
Reconfigurable Intelligent Surface-Aided Grant-Free Access for Uplink URLLC
Dick Carrillo Melgarejo, Charalampos Kalalas, Arthur Sousa de Sena +1
Reconfigurable intelligent surfaces (RISs) have been recently considered as one of the emerging technologies for future communication systems by leveraging the tuning capabilities…
On Integer-Forcing Precoding for the Gaussian MIMO Broadcast Channel
Danilo Silva, Gabriel Pivaro, Gustavo Fraidenraich +1
Integer-forcing (IF) precoding, also known as downlink IF, is a promising new approach for communication over multiple-input multiple-output (MIMO) broadcast channels. Inspired by…
On the Exact Distribution of Mutual Information of Two-user MIMO MAC Based on Quotient Distribution of Wishart Matrices
Gabriel Pivaro, Santosh Kumar, Gustavo Fraidenraich
We propose the exact calculation of the probability density function (PDF) and cumulative distribution function (CDF) of mutual information (MI) for a two-user MIMO MAC network ove…
Outage Probability for Multi-Hop Full-Duplex Decode and Forward MIMO Relay
G. F. Pivaro, G. Fraindenraich
In this paper, a multi-hop (MH) decode-and-forward (DF) multiple-input multiple-output (MIMO) relay network has been studied. To consider a more realistic scenario, Full-Duplex (FD…
On the Exact and Approximate Eigenvalue Distribution for Sum of Wishart Matrices
S. Kumar, G. F. Pivaro, G. Fraidenraich +1
The sum of Wishart matrices has an important role in multiuser communication employing multiantenna elements, such as multiple-input multiple-output (MIMO) multiple access channel…
