    Conference lecture
    Open Access
    We propose a novel Active Learning framework capable to train effectively a convolutional neural network for semantic segmentation of medical imaging, with a limited amount of training labeled data. Our contribution is a ...
  • Using static connections to improve elastic optical networks performance 

    Comellas Colomé, Jaume; Vicario, L.; Junyent Giralt, Gabriel (Optical Society of American (OSA), 2017)
    Conference report
    Restricted access - publisher's policy
    Network resources are poorly used in Elastic Optical Networks under dynamic traffic conditions. A hybrid scheme where some resources are statically allocated and the remaining ones are devoted to dynamic traffic, is proposed ...
  • Performance comparison of up-link and down-link techniques under DUDe strategy for heterogeneous networks 

    Wang, Hui; García Lozano, Mario; Mutafungwa, Edward; Yin, Xuefeng; Ruiz Boqué, Sílvia (2017)
    Conference report
    Restricted access - publisher's policy
    This paper provides new insights about the performance of Down-link and Up-link Decoupling (DUDe) when compared with Cell Range Expansion (CRE) combined with enhanced Inter-Cell Interference Coordination (eICIC). Instead ...
  • An improved dynamic wavelength assignment in statistical UDWDM-PONs 

    Sales Zaragoza, Vicente; Segarra Mullerat, Josep; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    Dynamic wavelength assignment (DWA) is investigated for managing ultra-dense wavelength division multiplexing-passive optical networks (UDWDM-PONs). The optical network units (ONUs) own lasers under limited thermal tunability ...
  • Non parametric coding of speech by means of a MLP with hints 

    Hernández, G; Monte Moreno, Enrique; Mariño Acebal, José Bernardo (Springer, 1997)
    Conference report
    Restricted access - publisher's policy
    This paper presents a non parametric compression system which makes use of the fact that a MLP has an internal representation of the data in the hidden layer. The system that we present makes a compression by using 4 or 8 ...
  • Modelling approach used in the real time emulator of the rainbow demostrator 

    Díaz Romero, M. del Pilar; Olmos Bonafé, Juan José; Berberana, Ignacio; Casadevall Palacio, Fernando José (Institute of Electrical and Electronics Engineers (IEEE), 1997)
    Conference report
    Open Access
    An overview of the main characteristics of the real time emulator (RTE) to be implemented in the context of the Rainbow project is presented. First of all, the RTE functional description is shown in order to justify the ...

    This paper presents experimental results for a SpatialDivision Multiple Access cellular mobile communicationssystem. The basestation antenna array testbedused to obtain the results is described in addition tosophisticated ...
  • Minimum PER user-energy profile for massive SIC receivers under an average energy constraint 

    Sala Álvarez, José; Rey Micolau, Francesc; Villares Piera, Nemesio J.; Molina Oliveras, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference lecture
    Restricted access - publisher's policy
    Interference may pose a severe limitation to massive wireless multiple access unless the central receiver is endowed with strong multipacket reception capabilities. In that respect, Interference Cancellation (IC) has been ...
