  • Multimodal planar monopole filtenna for 5G applications 

    Ribó Pal, Miquel; Cabedo Fabrés, Marta; Pradell i Cara, Lluís; Blanch Boris, Sebastián; Ferrando Bataller, Miquel (Elsevier, 2024-06)
    Article
    Open Access
    This paper presents a novel planar filtering antenna (filtenna) with simple layout based on tightly-coupled different-length monopoles. Its design methodology is based on an even-mode/odd-mode decomposition of the monopole ...
  • Asymptotic analysis of near-field coupling in massive MISO and massive SIMO systems 

    Martí Espelt, Aniol; Riba Sagarra, Jaume; Lamarca Orozco, M. Meritxell; Gràcia Sabaté, Francesc Xavier (2024-06-17)
    Article
    Open Access
    This paper studies the receiver to transmitter antenna coupling in near-field communications with massive arrays. Although most works in the literature consider that it is negligible and approximate it by zero, there is ...
  • Quadratic detection in noncoherent massive SIMO systems over correlated channels 

    Vila Insa, Marc; Martí Espelt, Aniol; Riba Sagarra, Jaume; Lamarca Orozco, M. Meritxell (Institute of Electrical and Electronics Engineers (IEEE), 2024-06-14)

  • Toxicity in multilingual machine translation at scale 

    Ruiz Costa-jussà, Marta; Smith, Eric; Ropers, Christophe; Licht, Daniel; Maillard, Jean; Ferrando Monsonís, Javier; Escolano Peinado, Carlos (Association for Computational Linguistics, 2023)
    Conference report
    Open Access
    Machine Translation systems can produce different types of errors, some of which are characterized as critical or catastrophic due to the specific negative impact that they can have on users. In this paper we focus on one ...
  • SegAugment: maximizing the utility of speech translation data with segmentation-based augmentations
