    Article
    Open Access
    With the goal of enabling ultrareliable and low-latency wireless communications for industrial internet of things (IIoT), this paper studies the use of energy-based modulations in noncoherent massive single-input multiple-output ...
  • SegAugment: maximizing the utility of speech translation data with segmentation-based augmentations 

    Tsiamas, Ioannis; Rodríguez Fonollosa, José Adrián; Ruiz Costa-jussà, Marta (Association for Computational Linguistics, 2023)
    Conference report
    Open Access
    End-to-end Speech Translation is hindered by a lack of available data resources. While most of them are based on documents, a sentence-level version is available, which is however single and static, potentially impeding ...
  • Cirrus scenes in Barcelona, Spain: Geometrical and optical properties and radiative effects
