    This paper addresses the problem of resource allocation and quality of service (QoS) management in a downlink communication system where the users are allowed to be attached to and receive data from one or several ...
  • 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 ...
  • Use of the available information for adequate step-size actualization 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni (1987)
    Conference report
    Open Access
    This paper deals with the use of the available information for the update of the step-size in gradient-based adaptive methods. Several proposals are made and due to the relatively high computational cost, more efficient ...
  • Design and implementation of a 2048FFT capture spectrum analyzer 

    Vázquez Grau, Gregorio (1985)
    Conference report
    Open Access
    This paper describes the hardware implementation of a digital spectrum analyzer which, by using a capture process of the signal under processing, performs some non parametric signal processing techniques. All the possibilities ...
  • Bit-slice implementation of a linear predictive vocoder 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni (1985)
    Conference report
    Open Access
    A digital 16-bit high-speed general-purpose signal-processor is shown. The main objective has been the implementation of a linear predictive vocoder for obtaining real-time speech compression. For real-time digital speech ...
  • 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
    Restricted access - publisher's policy
    In this paper, we focus on a broadcast multiuser multiple-input multiple-output (MIMO) system in a network with short links. In this scenario we consider that some terminals harvest power and, thus, recharge their ...
  • Energy-aware broadcast MU-MIMO precoder design with imperfect battery knowledge 

    Rubio López, Javier; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    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 ...
