    Energy efficient spatial modulation-aided uplink and downlink designs for future millimeterwave (mmWave) large-scale multiple-input multiple-output (MIMO) systems are considered. Two novel uplink transceivers are proposed ...
  • Wideband receive spatial modulation with time domain pre-equalizer for large MIMO systems 

    Raafat Hosny Mohamed Fahm, Ahmed; Agustín de Dios, Adrián; Vidal Manzano, José (2018)
    Conference report
    Open Access
    Receive spatial modulation (RSM) schemes are promising for massive multiple-input-multiple-output (MIMO) systems at millimeter wave (mmWave) bands because they require reduced complexity and low consumption hardware at the ...
  • Deep learning for experimental hybrid terrestrial and satellite interference management 

    Henarejos, Pol; Vázquez Oliver, Miguel Ángel; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    Interference Management is a vast topic present in many disciplines. The majority of wireless standards suffer the drawback of interference intrusion and the network efficiency drop due to that. Traditionally, interference ...
  • Modelling of airborne pollen dispersion in the atmosphere in the Catalonia region, Spain: model description, emission scheme and evaluation of model performance for the case of Pinus 

    Sicard, Michaël; Jorba Casellas, Oriol; Izquierdo Miguel, Rebeca; Alarcón Jordán, Marta; De Linares, Concepción; Belmonte Soler, Jordina (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
    Conference lecture

    Pollination is a biologically-relevant process that affects the structure of ecosystems since pollen contributes to determine the spatial distribution of plant species. It is thus of interest for mapping ecosystem services ...
  • Video object linguistic grounding 

    Herrera-Palacio, Alba; Ventura, Carles; Giró Nieto, Xavier (Association for Computing Machinery (ACM), 2019)
    Conference lecture

    The goal of this work is segmenting on a video sequence the objects which are mentioned in a linguistic description of the scene. We have adapted an existing deep neural network that achieves state of the art performance ...
  • Channel-aware energy allocation for throughput maximization in massive low-rate multiple access 

    Molina Oliveras, Francesc; Sala Álvarez, José; Rey Micolau, Francesc; Villares Piera, Nemesio Javier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    A multiple access (MA) optimization technique for massive low-rate direct-sequence spread spectrum communications is analyzed in this work. A dense network of users transmitting at the same rate to a common central node ...
  • A proof of de Bruijn identity based on generalized Price’s theorem 

    Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    This paper shows that de Bruijn identity, which relates entropy with Fisher information, can be obtained as a particular case of an immediate generalization of Price’s theorem, which is a tool used in the analysis of ...
  • Multi-satellite cycle-slip detection and exclusion using the noise subspace of residual dynamics 

    Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de; Juan Zornoza, José Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    Real-time detection of cycle-slips on undifferenced carrier-phase measurements is an important task to properly exclude wrong phase trackers from precise positioning algorithms. The detection is especially challenging in ...
  • Multi-view 3D face reconstruction in the wild using siamese networks 

    Ramon, Eduard; Escur, Janna; Giró Nieto, Xavier (Computer Vision Foundation, 2019)
    Conference report
    Open Access
    In this work, we present a novel learning based approach to reconstruct 3D faces from a single or multiple images. Our method uses a simple yet powerful architecture based on siamese neural networks that helps to extract ...
  • On the coordination of base stations in ultra dense cellular networks 

    Aravanis, Alexios; Muñoz Medina, Olga; Pascual Iserte, Antonio; di Renzo, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Ultra dense networks (UDNs) allow for efficient spatial reuse of the spectrum, giving rise to substantial capacity and power gains. However, recent findings have demonstrated that the reduction of inter-site distances after ...
  • The TALP-UPC machine translation systems for WMT19 news translation task: pivoting techniques for low resource MT 

    Casas Manzanares, Noé; Rodríguez Fonollosa, José Adrián; Escolano Peinado, Carlos; Basta, Christine Raouf Saad; Ruiz Costa-Jussà, Marta (Association for Computational Linguistics, 2019)
    Conference report
