Using the Power Delay Profile to Accelerate the Training of Neural Network-Based Classifiers for the Identification of LOS and NLOS UWB Propagation Conditions
(Institute of Electrical and Electronics Engineers, 2020)
[Abstract]: Ultra-wideband (UWB) technology enables centimeter-level localization systems based on the accurate estimation of the actual distance between transmitter and receiver, by means of the precise estimation of the ...
Time-Modulated Arrays Controlled With Sinusoidal Pulsewidth Modulation
(Institute of Electrical and Electronics Engineers, 2020)
[Abstract]: In this letter, sinusoidal pulsewidth modulation (PWM) is applied to the design of time-modulated arrays (TMAs). The array excitations are modulated using PWM-synthesized sine waveforms. This provides increased ...
An IoT system for a smart campus: Challenges and solutions illustrated over several real-world use cases
(Elsevier, 2024-04)
[Abstract]: This article discusses the development of an IoT system for monitoring and controlling various devices and systems from different vendors. The authors considered key challenges in IoT projects, such as ...
A TMA-FDA Approach for Two-Beam Steering
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: Frequency diverse arrays (FDAs) allow the synthesis of dot-shaped radiated patterns in the range-angle space by applying frequency offsets to the antenna elements. Conventional FDAs are usually implemented with ...
Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: The application of frequency offsets to the elements of a conventional phased array with variable phase shifters (VPSs) leads to frequency diverse arrays (FDAs) with the ability to provide range-angle spatial ...
Reply to “Comments on ‘Combining Switched TMAs and FDAs to Synthesize Dot-Shaped Beampatterns”’
(Institute of Electrical and Electronics Engineers, 2021)
[Abstract]: It is noted that the main innovation contained lies in the consideration of frequency diverse arrays (FDAs) feeding networks made up of time-modulating switches (hence, the term TMA-FDA) instead of phase shifters. ...
Utilization of a Mobile Application for Motor Skill Evaluation in Children
(MDPI AG, 2021-01-12)
[Abstract]
The detection of needs in educational reinforcement must be done in the early stages of childhood during primary education to improve the acquisition of motor skills. An adequate early intervention can solve ...
Service-Learning methodology to develop Bachelor’s Thesis in Information and Computer Science Degrees
(PKP Publishing Services Network, 2024)
[Abstract]: Service-Learning (SL) is a powerful methodology to acquire competences and values in Higher Education. However, there is still no widespread use in Information and Computer Science (ICS) degrees where most of ...
