Soft-Decision Decoding for LDPC Code-Based Quantitative Group Testing
Marvin Xhemrishi, Johan Östman, Alexandre Graell i Amat
We consider the problem of identifying defective items in a population with non-adaptive quantitative group testing. For this scenario, Mashauri et al. recently proposed a low-dens…
On Local Mutual-Information Privacy
Khac-Hoang Ngo, Johan Östman, Alexandre Graell i Amat
Local mutual-information privacy (LMIP) is a privacy notion that aims to quantify the reduction of uncertainty about the input data when the output of a privacy-preserving mechanis…
Timely Status Updates in Slotted ALOHA Networks With Energy Harvesting
Khac-Hoang Ngo, Giuseppe Durisi, Andrea Munari +2
We investigate the age of information (AoI) in a scenario where energy-harvesting devices send status updates to a gateway following the slotted ALOHA protocol and receive no feedb…
Age of Information in Slotted ALOHA With Energy Harvesting
Khac-Hoang Ngo, Giuseppe Durisi, Alexandre Graell i Amat +2
We examine the age of information (AoI) of a status update system that incorporates energy harvesting and uses the slotted ALOHA protocol. We derive analytically the average AoI an…
Unsourced Multiple Access with Common Alarm Messages: Network Slicing for Massive and Critical IoT
Khac-Hoang Ngo, Giuseppe Durisi, Alexandre Graell i Amat +3
We investigate the coexistence of massive and critical Internet of Things (IoT) services in the context of the unsourced multiple access (UMA) framework introduced by Polyanskiy (2…
