  • Efficient bit-level design of an on-board digital TV demultiplexer 

    Sala Álvarez, José; Pagès Zamora, Alba Maria; Vázquez Grau, Gregorio (1998)
    Conference report
    Open Access
    A bit-level description of the signal processing stage of an on-board integrated VLSI multi-carrier demodulator is presented in this paper, along with a description of the optimization procedure that has been developed for ...
  • Design and implementation of a DVB on-Board multi-carrier demodulator 

    Sala Álvarez, José; Pagès Zamora, Alba Maria; Sergio, Calvo; Prat Gomà, Josep Joan (1998)
    Conference report
    Open Access
    A description of the signal processing stage of an on-board integrated VLSI multi-carrier demodulator at the demultiplexing level is presented, along with a description of the optimization procedure that has been developed ...
  • A statistical reference criterion for adaptive filtering 

    Sala Álvarez, José; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 1996)
    Conference report
    Open Access
    A cost function for adaptive filtering is proposed, based on the statistical reference criterion. The purpose of this criterion is to enforce a given probability density function at the output of a system. The only ...
  • Adaptive blind equalization and demodulation without channel and signal parameter extraction 

    Sala Álvarez, José; Vázquez Grau, Gregorio (1994)
    Conference report
    Open Access
    The problem of filtering a source of known statistics in noise and/or interference of unknown statistics is addressed in this paper. In a general framework, the optimum estimation (detection) of the desired signal requires ...
  • Global beamforming and demodulation for linearly modulated signals 

    Sala Álvarez, José; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 1994)
    Conference report
    Open Access
  • Separation of digital communication signals through joint space-time decorrelation 

    Sala Álvarez, José; Vázquez Grau, Gregorio (1994)
    Conference report
    Open Access
    In this paper we derive the optimum linear algorithm for the separation by an array of a given number of cyclostationary signals of the type encountered in digital communications. Spatially and temporally uncorrelated noise ...
  • A distributed arithmetics architecture for quantization SNR improvement based on LUT recoding 

    Rubio Fernández, José; Sala Álvarez, José (Servicio de Publicaciones Universidad de Vigo, 1999)
    Conference report
    Open Access
  • HISPANET: a digital television/multimedia payload 

    Sala Álvarez, José; Sergio, Calvo; Pagès Zamora, Alba Maria; Vázquez Grau, Gregorio; Riba Sagarra, Jaume (European Spatial Agengy (ESA), 1998)
    Conference report
    Open Access
  • A fast OFDM-CDMA user demultiplexing architecture 

    Marti Puig, Pere; Sala Álvarez, José (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Conference report
    Open Access
    A fast algorithm based on a butterfly structure is presented that demultiplexes the symbols of a particular type of MC-MA (multi-carrier multiple-access) modulation previously proposed for indoor radio communications. A ...
  • Pointing correction in an adaptive array for communications 

    Lagunas Hernandez, Miguel A.; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 1991)
    Conference report
    Open Access
    The authors discuss DSP procedures for pointing correction in adaptive arrays which uses a spatial reference to form the optimum beam (generalized sidelobe canceller, GSLC). The problem of adequate pointing arises from ...
