  • Inclusion of gradient-based schemes in high resolution method 

    Vázquez Grau, Gregorio; Vallverdú Bayés, Francesc (1988)
    Conference report
    Open Access
    This paper deals with the inclusion of adaptive schemes in high-resolution methods. Past works refer gradient and conjugated gradient approaches of Pisarenko’s spectral line decomposition method for sinusoidal in white ...
  • Parametric envelope in LPC speech coders 

    Moreno Bilbao, M. Asunción; Lagunas Hernandez, Miguel A.; Vallverdú Bayés, Francesc (1985)
    Conference report
    Open Access
    During the last decade, many efforts have been devoted to the relative importance of associated functions like magnitude and phase of Fourier Transforms in image and signal bandwidth reduction. The reported work deals with ...
  • The normalized backpropagation and some experiments on speech recognition 

    Monte Moreno, Enrique; Mariño Acebal, José Bernardo (Springer, 1990)
    Conference report
    Open Access
    In the paper we present the theoretical development of the normalized backpropagation, and we compare it with other algorithms that have been presented in the literature. The algorithm that we propose is based on the idea ...
  • Medium Rate Speech Coding with Vector Quantization 

    Masgrau Gómez, Enrique José; Mariño Acebal, José Bernardo; Moreno Bilbao, M. Asunción (1989)
    Conference report

  • 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 ...
  • On the Use of Higher Order Information in SVD Based Methods 

    Vázquez Grau, Gregorio; Vallverdú Bayés, Francesc (1988)
    Conference report

  • 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 ...
