  • Simultaneous wireless information and power transfer in multiuser MIMO systems 

    Rubio López, Javier; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report

    This paper addresses the problem of precoder design in a MIMO broadcast scenario where the terminals are battery-powered devices provided with energy harvesting capabilities. Models for the power consumption of the RF ...
  • Filtrado transversal adaptativo de varianza constante para la ecualización de canal 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni; Sánchez Umbría, Juan; Oliveras Vergés, Albert (1989)
    Conference report
    Open Access
    This paper describes the problem of lineal filtering of noisy data under a Maximum Likelihood objective. In this sense, the paper shows that a weighted square error cost function deals and it is necessary to weight the ...
  • 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 ...

  • 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 ...
  • System identification through first and second order information from the periodogram 

    Vázquez Grau, Gregorio; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    Email Print Request Permissions The use of first- and second-order information in the characterization of linear systems is considered. Consideration is given to the case when this information is not available but some ...
  • Data pre-processing for high-resolution adaptive algorithms 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    The inclusion of adaptive methods in high-resolution spectral estimation algorithms is considered. The generation of a complete family of spectral estimators from the normalized maximum-likelihood method (MLM) is discussed. ...
