A QoE-driven traffic steering algorithm for LTE Networks
(2019-01-31)Due to the huge increase in traffic and services in mobile networks, network management has changed its main focus from Quality of Service (QoS) to a Quality of Experience (QoE) perspective. In addition, SON (Self Organizing ... -
Radio interference analysis tool based on GNU Radio
(2019-10-30)Avoiding interference is one of the main challenges in radio communications. Interference hunting is usually done with costly instruments. In this work, a cost efficient portable tool is described for interference analysis ... -
Ranura de Banda Ancha en Doble T Sobre Cavidad para Arrays Alimentados en Serie
(2019-09-16)A previous radiating element for series-fed arrays proposed by the authors and based on a Cavity-Backed Slot (CBS) is modified to improve its bandwidth. In order to do that, the slot is modified to reduce its resonance ... -
Re-inventing Multimode Interference Couplers Using Subwavelength Gratings
(European Physical Society, IEEE, The Optical Society, 2013)We use the concept of subwavelength grating (SWG) refractive-index-engineering to propose and experimentally demonstrate a reduced size, slotted 2x2 MMI coupler. We also present an ultra-broadband 2x2 MMI coupler which ... -
Real-time audio interaction in serious games for music learning
(2016-09-05)In this LBD, we present several Apps for playing while learning music or for learning music while playing. The core of all the games is based on the good performance of the real-time audio interaction algorithms developed ... -
Recent progress in subwavelength grating metamaterial engineered silicon photonic devices.
(2023)In this talk we present our recent advances in SWG metamaterial engineering. We will show a 1D-optical phased array composed of 112 evanescent-coupled surface emitting antennas with a length of 1.5 mm and fed by a compact ... -
Receptor coherente integrado ‘colorless’ de gran margen dinámico basado en un acoplador a 120º
(2014-09-09)Un receptor ‘colorless’ requerirá en su banda de operación de un elevado rechazo en modo común CMRR para reducir eficientemente la interferencia en banda base ocasionada por los canales colindantes al detectado y conseguir ... -
Recognizing complex gestures via natural interfaces
(2018-04-02)Natural interfaces have revolutionized the way we interact with computers. They have provided in many fields a comfortable and efficient mechanism that requires no computer knowledge, nor artificial controlling devices, ... -
Relaxation-Time Modeling for NQS Phenomena Characterization in High-Frequency Diodes.
(2023)AbstractÐA characterization methodology for nonquasi-static (NQS) phenomena in high frequency electron devices is carried out in this work. The proposed nonlinear diode model includes a S-parameters-based procedure for the ... -
Reparto de tráfico basado en métricas de rendimiento en escenarios con multiconectividad
(2019-10-30)Multi-connectivity (MC) is one of the most relevant features to be introduced in 5G networks, allowing users to simultaneously aggregate radio resources from several network nodes to improve both reliability and data rates. ... -
Reparto de tráfico en redes 5G con segmentación.
(2023)In 5G and beyond wireless systems, Network Slicing (NS) feature will enable the coexistence of extremely different services. In sliced Radio Access Networks (RANs), an optimal traffic sharing among cells is key to guarantee ... -
