  • Adaptive spectrum estimation with linear constrains 

    Vázquez Grau, Gregorio; Vallverdú Bayés, Francesc (1988)
    Conference report
    Open Access
    A general constrained adaptive metbod is developed to be applied to the spectral estimation problem. The method presented can be used in a wide range of situatious, this is, we can get different estimators wíth it. The ...
  • Leveraging online user feedback to improve statistical machine translation 

    Formiga, Lluís; Barrón-Cedeño, Alberto; Marquez, Lluis; Henriquez, Carlos A; Mariño Acebal, José Bernardo (2015-09-01)
    Article
    Open Access
    In this article we present a three-step methodology for dynamically improving a statistical machine translation (SMT) system by incorporating human feedback in the form of free edits on the system translations. We target ...

  • Cross spectrum ML estimate 

    Lagunas Hernandez, Miguel A.; Santamaría Pérez, María Eugenia; Gasull Llampallas, Antoni; Moreno Bilbao, M. Asunción (Institute of Electrical and Electronics Engineers (IEEE), 1985)
    Conference report
    Open Access
    This work reports how to include general concepts of the one-dimensional MLM procedure in a two-channel problem of cross-spectrum estimation. It is shown in the sequel that there is no any problem in extrapolating the ...
  • Método MLNq para arrays de alta resolución 

    Gasull Llampallas, Antoni; Lagunas Hernandez, Miguel A.; Fernández Rubio, Juan Antonio; Moreno Bilbao, M. Asunción (Universidad de Sevilla, 1984)
    Conference report
    Open Access
    Spectral analysis techniques are used to bearing estimation problem. Each one of this gives a different array beamforming. We show here a generalized normalized Maximum Likehood Method which present a high resolution ...
  • A direct approximation technique for designing digital equalizers with simultaneous specification of magnitude and phase 

    Mariño Acebal, José Bernardo; Figueiras Vidal, Aníbal R. (Georgi, 1978)
    Conference report
    Open Access
    A new direct method for designing nonrecursive and recursive digital equalizers approximating specified attenuation and phase responses is introduced . This method allows to control both magnitude and phase characteristics ...
  • Randomizing ties in a sign radar detector 

    Figueiras Vidal, Aníbal R.; Mariño Acebal, José Bernardo; Lagunas Hernandez, Miguel A.; García Gómez, Ramón; Martín Funke, Enrique (Imperial College Press (ICP), 1981)
    Conference report
    Open Access
    A general formulation to consider the effects of typical randomization methods (RMs) for a digital application of Generalized Sign Test (GST) detector in Radar is introduced. A first approximation leads us to some basic ...
  • Envelope and instantaneous phase considerations in speech modelling 

    Moreno Bilbao, M. Asunción; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    The authors present a low-bit-rate coding system where the envelope and instantaneous phase of the residual are used. A time-varying filter (short-delay filter) is excited by a signal composed by a parametric version of ...
