    Conference report
    Open Access
    Mission Critical Services (MCS) are gaining interest among network operators to offer alternative communications than conventional trunked radio systems. They promise a simplified management of cloud and radio resources ...
  • One shot learning for generic instance segmentation in RGBD videos 

    Lin, Xiao; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (Scitepress, 2019)
    Conference report
    Open Access
    Hand-crafted features employed in classical generic instance segmentation methods have limited discriminative power to distinguish different objects in the scene, while Convolutional Neural Networks (CNNs) based semantic ...
  • Positioning and timing in the MIMO-gnss framework 

    García Molina, J. A.; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    This paper discusses about GNSS-based positioning and timing in challenging propagation conditions for receivers featuring an array of antennas with an arbitrary distribution. In particular, the positioning and timing ...
  • On the influence of the channel impulsional response estimation on the performance of a linear interference canceller for a DS/CDMA system 

    Díaz Romero, M. del Pilar; Agustí Comes, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1994)
    Conference report
    Open Access
    In a code division multiple access (CDMA) mobile radio communication system, interference from other users is one of the most critical drawbacks due to the lack of perfect orthogonality between user access codes. So far, ...
  • Dynamic selection and update of digital predistorter coefficients for power amplifier linearization 

    Pham, Thi Quynh Anh; López Bueno, David; Montoro López, Gabriel; Gilabert Pinal, Pere Lluís
    Conference lecture
