    A generic software tool to evaluate the impact of ionospheric disturbances is presented, including low and high latitude physically-based models, and low and high frequency fluctuations. This tool has been developed ...
  • One-shot capacity bounds on the simultaneous transmission of public and private information over quantum channels 

    Salek Shishavan, Farzin; Anshu, Anurag; Hsieh, Min-Hsiu; Jain, Rahul; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Restricted access - publisher's policy
    We aim to study the optimal rates of transmission of public and private classical information over a quantum channel in the most general channel model. To this end, we discuss a scenario in which a quantum channel is being ...

    En este trabajo se presenta tanto el diseño como la experimentación de un Laboratorio Virtual de Comunicaciones Analógicas y Digitales: LaViCAD. Mediante LaViCAD se pueden experimentar y verificar diferentes aplicaciones ...
  • Modeling and control of a three-phaseg grid-connected inverter under fault conditions 

    Rolán Blanco, Alejandro; Giménez Febrer, Pedro Juan; Yague, Sauro J.; Bogarra Rodríguez, Santiago (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    The aim of this paper is to study the behavior of a three-phase inverter with an RL filter powered by a renewable energy source and connected to a grid under fault conditions. The novelty of the work lies in proposing a ...
  • A practical approach for NLOS mitigation in location-aware networks 

    René, Játiva A.; Valdiviezo, Santiago; Espinosa, Andy; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
