      Article
      Open Access
      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 Javier; 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 ...
