Underwater Positioning System Based on Drifting Buoys and Acoustic Modems
(MDPI, 2023-03-23)GNSS (Global Navigation Satellite System) positioning is not available underwater due to the very short range of electromagnetic waves in the sea water medium. In this article a LBL (Long Base Line) acoustic repeater system ... -
Using the Uniform Theory of Diffraction to Analyze Radio Wave Propagation along Urban Street Canyons for Device-to-Device Communication
(IOAP-MDPI, 2023-01-25)This paper examines the propagation of radio waves in so-called urban street canyons through formulations based on Geometrical Optics (GO) and the Uniform Theory of Diffraction (UTD). As this type of environment comprises ... -
Using XAI in the Clock Drawing Test to reveal the cognitive impairment pattern.
(World Scientific, 2023-02-16)he prevalence of dementia is currently increasing worldwide. This syndrome produces a deteriorationin cognitive function that cannot be reverted. However, an early diagnosis can be crucial for slowing itsprogress. The Clock ... -
Victim Detection and Localization in Emergencies
(IOAP-MPDI, 2022-11-02)Detecting and locating victims in emergency scenarios comprise one of the most powerful tools to save lives. Fast actions are crucial for victims because time is running against them. Radio devices are currently omnipresent ... -
Wideband Ultrasonic Acoustic Underwater Channels: Measurements and Characterization.
(IEEE, 2020-02-12)In this work we present the results of a measurement campaign carried out in the Mediterranean sea aimed at characterizing the underwater acoustic channel in a wideband at ultrasonic frequencies centered at 80 kHz with ... -
Wireless backhaul: Performance Modelling and Impact on User Association for 5G.
(IEEE, 2018-02-22)Wireless technology is the strongest contender for catering for the 5G backhaul (BH) stipulated performance, where optical fiber is unavailable. In the presence of ultra-dense networks, such occurrences are exponentially ...
