Architecture for Multi-Technology Real-Time Location Systems
(Multidisciplinary Digital Publishing Institute, 2013)
[Abstract]The rising popularity of location-based services has prompted considerable research in the field of indoor location systems. Since there is no single technology to support these systems, it is necessary to consider ...
Wideband Hybrid Precoding Using Time Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020-08-05)
[Abstract]
Hybrid digital-analog precoding is a cost effective solution for transmitting over the large bandwidths and huge antenna arrays available in the millimeter wave frequency bands. In this work we focus on the ...
User Grouping for the Uplink of Multiuser Hybrid mmWave MIMO
(Institute of Electrical and Electronics Engineers, 2020-03-16)
[Abstract] Hybrid analog/digital schemes for precoding/combining have proved to be a low-complexity and/or low-power strategy to obtain reasonable beamforming gains in multiuser millimeter-wave (mmWave) multiple-input ...
Exploratory Research on Sweetness Perception: Decision Trees to Study Electroencephalographic Data and Its Relationship with the Explicit Response to Sweet Odor, Taste, and Flavor
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Using implicit responses to determine consumers’ response to different stimuli is becoming a popular approach, but research is still needed to understand the outputs of the different technologies used to collect data. ...
Emerging Paradigms and Architectures for Industry 4.0 Applications
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
[Abstract]: The Fourth Industrial Revolution (4IR), called “Industry 4.0” in Europe, “Industrial Internet of Things” in North America, or “Made in China 2025” in China, blurs the boundaries between the physical, digital ...
On the Feasibility of Time-Modulated Arrays for Digital Linear Modulations: a Theoretical Analysis
(Institute of Electrical and Electronics Engineers, 2014)
[Abstract] Wireless communications are widely based on linear digital modulation methods, which introduce the digital baseband information in the amplitude and/or in the phase of a carrier sinusoid. Time-modulated arrays, ...
Dual-Beam Steerable TMAs Combining AM and PM Switched Time-Modulation
(MDPI, 2022)
[Abstract] Wireless sensor networks (WSN) are increasingly requiring directional antennas that not only provide higher capacity, security, transmission range or robustness against interference, but also contribute with ...
An overview of IoT architectures, technologies, and existing open-source projects
(Elsevier, 2022-11)
[Abstract]: Today’s needs for monitoring and control of different devices in organizations require an Internet of Things (IoT) platform that can integrate heterogeneous elements provided by multiple vendors and using ...
Multicamera edge-computing system for persons indoor location and tracking
(Elsevier, 2023-12)
[Abstract]: This paper presents an indoor person localization and tracking system that uses multiple smart cameras equipped with artificial intelligence (AI) accelerators serving as edge-computing nodes. Our main contributions ...
Design, Implementation, and Practical Evaluation of a Voice Recognition Based IoT Home Automation System for Low-Resource Languages and Resource-Constrained Edge IoT Devices: A System for Galician and Mobile Opportunistic Scenarios
(IEEE, 2023)
[Abstract]: Systems with voice control are an attractive option for increasing technological integration, not only for people with little knowledge on technology or constrained Internet access, but also for people with ...
