    En sistemas de transmisión de alta velocidad en canales wireless, donde el espectro es un recurso altamente limitado, se hace necesaria la implementación de algoritmos de reparto de los recursos si se pretende cumplir ...
  • Asymptotic equivalence between the unconditional maximum likelihood and the square-law nonlinearity symbol timing estimation 

    López Salcedo, José Antonio; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-01-31)
    Article
    Open Access
    This paper provides a systematic approach to the problem of nondata aided symbol-timing estimation for linear modulations. The study is performed under the unconditional maximum likelihood framework where the ...
  • DA-GLRT burst detection and synchronization based on a chirp-like preamble 

    Rodríguez, E; Lamarca Orozco, M. Meritxell; López Salcedo, José Antonio; Rey Micolau, Francesc; Riba Sagarra, Jaume; Sala Álvarez, José; Vázquez Grau, Gregorio; Villares Piera, Nemesio J.; Jalón, A (2008)
    Conference report
    Restricted access - publisher's policy
    A specific preamble for the tasks of signal detection and synchronization in burst digital communications is presented. The preamble resembles a chirp signal used in RADAR applications. Its main benefit is that it allows ...
  • Detection of PPM-UWB random signals 

    López Salcedo, José Antonio; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008-04-23)
    Article
    Open Access
    This paper focuses on the symbol detection problem of random pulse-position modulation (PPM) ultrawideband (UWB) signals in the absence of interframe interference. Particular attention is devoted to severely time-varying ...

  • Waveform-independent frame-timing acquisition for UWB signals 

    López Salcedo, José Antonio; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-01-31)
    Article
    Open Access
    In this paper, the problem of frame-level symbol timing acquisition for UWB signals is addressed. The main goal is the derivation of a frame-level timing estimator which does not require any prior knowledge of neither ...
