    This paper discusses the exploitation of data analytics for supporting the operation of Radio Resource Management (RRM) in the Next Generation Radio Access Network (NG-RAN), analysing the need for standardised and open ...
  • Experimental assessment of 10 Gbps 5G multicarrier waveforms for high-layer split U-DWDM-PON-based fronthaul 

    Sarmiento Hernández, Samael; Altabas, Jose Antonio; Spadaro, Salvatore; Lázaro Villa, José Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2019-05-15)
    Article
    Open Access
    The current constant growth in mobile networks' traffic demands caused by the popularization of cloud and streaming services on personal devices, requires architectural changes so as to fulfill all new 5G mobile network ...
  • Distributed feedback-aided subspace concurrent opportunistic communications 

    Borràs Pino, Jordi; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture

    This paper deals with the distributed subspace agreement problem for opportunistic communications in time division duplex (TDD) distributed networks. Since scenario-adapted opportunistic transmission schemes rely on locally ...
  • Low-complexity switching network design for hybrid precoding in mmWave MIMO systems 

    Molina Oliveras, Francesc; Borràs Pino, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report

    This paper deals with the design of a hybrid precoder for millimeter-wave MIMO systems. For the sake of concreteness, we consider an analog processing stage composed of a switching network with analog combining. The main ...
  • Digital predistorters go multidimensional: DPD for concurrent multiband envelope tracking and outphasing power amplifiers 

    Gilabert Pinal, Pere Lluís; Montoro López, Gabriel; Vegas Garcia, Ángel; Ruiz Lavin, Maria de las Nieves; García García, José Ángel (2019-05-01)
    Article
    Open Access
    Over at least the last two decades, digital predistortion (DPD) has become the most common and widespread solution to cope with the power amplifier's (PA's) inherent linearity-versus-efficiency tradeoff. When compared with ...
  • Orchestrating virtual slices in data centre infrastructures with optical DCN 

    Pagès Cruz, Albert; Agraz Bujan, Fernando; Montero Herrera, Rafael; Landi, Giada; Capitani, Marco; Gallico, Domenico; Biancani, Matteo; Nejabati, Reza; Simeonidou, Dimitra; Spadaro, Salvatore (2019-07-01)
    Article
    Restricted access - publisher's policy
    The emergence of new paradigms and services is pushing the limits of nowadays cloud infrastructures. It is a fact that current solutions lack in the flexibility and configurability to adapt to heterogeneous requirements ...
  • Enable advanced QoS-aware network slicing in 5G networks for slice-based media use cases 

    Wang, Qi; Alcaraz Calero, Jose; Ricart Sánchez, Rubén; Barros Weiss, Maria; Spadaro, Salvatore (2019-01-01)
    Article
    Open Access
    Media use cases for emergency services require mission-critical levels of reliability for the delivery of media-rich services, such as video streaming. With the upcoming deployment of the fifth generation (5G) networks, a ...

  • A statistical model from information theory to explain Zipf's law of brevity 

    Hernández Fernández, Antonio; González Torre, Iván; Lacasa, Lucas; Kello, Christopher; Luque Serrano, Bartolome (Basque Center on Cognition, Brain and Language, 2019)
    Conference lecture
    Restricted access - publisher's policy
    Brevity and frequency are two crucial factors in the processes of statistical learning. The compression principle had already been used previously to explain the origin of Zipf’s law for the frequency of words. Here we use ...
  • Log-normal distribution in acoustic linguistic units 

    González Torre, Iván; Lacasa, Lucas; Kello, Christopher; Luque Serrano, Bartolome; Hernández Fernández, Antonio (Basque Center on Cognition, Brain and Language, 2019)
    Conference lecture
    Restricted access - publisher's policy
    In this work we verify with accuracy that acoustically transcribed durations of linguistic units at several scales (phonemes, words and Breath Groups) comply with log-normal distribution. To do this we have used a very ...
