A Finite Block Length Achievability Bound for Low Probability of Detection Communication [PDF]

open access: yes2018 International Symposium on Information Theory and Its Applications (ISITA), 2018
Low probability of detection (or covert) communication refers to the scenario where information must be sent reliably to a receiver, but with low probability of detection by an adversary. Recent works on the fundamental limits of this communication problem have established achievability and converse bounds that are asymptotic in the block length of the

Self-Tuning of Signal Detection Level for Energy Detection-Based Carrier Sense in Low-Power Wide-Area Networks

open access: yesSensors
Carrier sense allows end devices to improve the communication quality through autonomous decentralization by consuming power. In particular, energy detection-based carrier sense can improve communication quality compared with peak detection-based carrier

Multitarget Tracking Algorithm Using Multiple GMPHD Filter Data Fusion for Sonar Networks

open access: yesSensors, 2018
Multitarget tracking algorithms based on sonar usually run into detection uncertainty, complex channel and more clutters, which cause lower detection probability, single sonar sensors failing to measure when the target is in an acoustic shadow zone, and ...
