    Article
    Accés obert
    Purpose: The purpose of this paper is to characterize the cyclical phases of the manufacturing industry in Spain and detect which industries have more influence on the Spanish business cycle. We assume that economic growth ...
  • Conditional maximum likelihood frequency estimation for staggered modulations 

    Riba Sagarra, Jaume; Vázquez Grau, Gregorio (1998)
    Text en actes de congrés
    Accés obert
    The use of spectrally efficient continuous phase modulations for mobile communications may lead to a serious performance degradation of the classical frequency error detectors (FEDs) due to the presence of self-noise. This ...
  • Conditional maximum likelihood timing recovery 

    Riba Sagarra, Jaume; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    The conditional maximum likelihood (CML) principle, well known in the context of sensor array processing, is applied to the problem of timing recovery. A new self-noise free CML-based timing error detector is derived. ...
  • Conditional maximum likelihood timing recovery: estimators and bounds 

    Riba Sagarra, Jaume; Sala i Álvarez, Josep; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-04-30)
    Article
    Accés obert
    This paper is concerned with the derivation of new estimators and performance bounds for the problem of timing estimation of (linearly) digitally modulated signals. The conditional maximum likelihood (CML) method is adopted, ...
  • Energy-efficient physical layer packet authenticator for machine-to-machine networks 

    Bartoli, Andrea; Hernández Serrano, Juan; León Abarca, Olga; Kountouris, Apostolous; Barthel, Dominique (Wiley-Blackwell, 2013-06)
    Article
    Accés restringit per política de l'editorial
    Machine-to-machine networks are spreading over every sector of our society due to their self-organisation capabilities. In these networks, thousands of devices are left unattended for years of operation without the possibility ...
  • Joint synchronization and symbol detection in asynchronous DS-CDMA systems 

    Rey Micolau, Francesc; Vázquez Grau, Gregorio; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Text en actes de congrés
    Accés obert
    The design of accurate estimators which also consider the noise term in low SNR scenarios is paramount for achieving optimal solutions and obtaining precise symbol detectors. Particularly, this paper estimates the propagation ...
  • Local scheduling techniques for memory coherence in a clustered VLIW processor with a distributed data cache 

    Gibert Codina, Enric; Sánchez, Jesús; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    Text en actes de congrés
    Accés obert
    Clustering is a common technique to deal with wire delays. Fully-distributed architectures, where the register file, the functional units and the cache memory are partitioned, are particularly effective to deal with these ...
