    This paper presents a new linearization method to compensate for the unwanted RF leakage that appears at the ouput of envelope tracking modulators (ETMs) when operating envelope tracking (ET) power amplifiers (PAs) with ...
  • Over the air computing for satellite networks in 6G 

    Martínez Gost, Marc; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference report
    Open Access
    6G and beyond networks will merge communication and computation capabilities in order to adapt to changes. As they will consist of many sensors gathering information from its environment, new schemes for managing these ...
  • Edge computing and communication for energy-efficient earth surveillance with LEO satellites 

    Martínez Gost, Marc; Leyva-Mayorga, Israel; Pérez Neira, Ana Isabel; Vázquez Oliver, Miguel Ángel; Soret, Beatriz; Moretti, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference lecture
    Open Access
    Modern satellites deployed in low Earth orbit (LEO) accommodate processing payloads that can be exploited for edge computing. Furthermore, by implementing inter-satellite links, the LEO satellites in a constellation can ...
  • Comparative study of upsampling methods for super-resolution in remote sensing 

    Salgueiro Romero, Luis Fernando; Marcello Ruiz, Javier; Vilaplana Besler, Verónica (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
    Conference report
    Open Access
    Many remote sensing applications require high spatial resolution images, but the elevated cost of these images makes some studies unfeasible. Single-image super-resolution algorithms can improve the spatial resolution of ...
  • Microwave-microfluidic measurement system optimization for bio-particle-sensing with coplanar-electrodes 

    Palacios Arias, César Augusto; Jofre Cruanyes, Marc; Jofre Cruanyes, Lluís; Trabal Pou, Arnau; Coll Beltran, Mercè; Rodríguez Gargallo, Marta; Romeu Robert, Jordi; Jofre Roca, Lluís (Íñigo Cuiñas Gómez, 2021)
    Conference report
    Restricted access - publisher's policy
    Microwave and microfluidic techniques may enable wireless monitoring and interaction with bio-particles, yet still is a largely uncharted territory. Fortunately, the requirements of microfluidics and microwave techniques ...
  • Forward method for vertical air motion estimation from frequency modulated continuous wave radar rain measurements 

    Salcedo Bosch, Andreu; Rocadenbosch Burillo, Francisco; Frasier, Steve; Domínguez Pla, Paula (MeteoSwiss (Bundesamt für Meteorologie und Klimatologie MeteoSchweiz), 2022)
    Conference report
    Open Access
    Vertically-pointed Frequency-Modulated Continuous-Wave (FMCW) radar measurements of rain are greatly influenced by strong vertical winds (vertical air motion, VAM) in convective rain scenarios. Particularly, 2nd order ...
