  • Re-optimisation of lpc filters for multi-pulse coded excitation 

    Pérez Palomar, Daniel; Sandler, M Price And M (Institution of Electrical Engineers, 1999-06)
    Article
    Open Access
    A method for optimising LPC filters in linear prediction based speech coders is described. The optimisation process compensates for errors incurred through coding the excitation signal, providing an improvement in the ...
  • Self-reference beamforming for DS-CDMA communication systems 

    Pérez Palomar, Daniel; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Conference report
    Open Access
    A self-reference beamforming algorithm, based on the inherent temporal redundancy structure presented by the spreading codes of direct sequence code division multiple access (DS-CDMA) systems, is proposed. It is derived ...
  • Self-reference spatial diversity processing for spread spectrum communications 

    Pérez Palomar, Daniel; Nájar Martón, Montserrat; Lagunas Hernandez, Miguel A. (2000-09)
    Article
    Restricted access - publisher's policy
    n this paper, the application of three blind (or selfreference) spatial diversity signal processing methods to Spread Spectrum (SS) communications is described. These methods do not require any kind of side information ...
