    • Simultaneous tracking and RSS model calibration by robust filtering 

      Castro Arvizu, Juan Manuel; Vila Valls, Jordi; Closas, Pau; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Received Signal Strength (RSS) localization is widely used due to its simplicity and availability in most mobile devices. The RSS channel model is defined by the propagation losses and the shadow fading. These parameters ...

    • Snapshot processing of high-order BOC signals in the cloud: on sensitivity and distortion effects 

      García Molina, José; Fernández Rubio, Juan Antonio; Weiler, R.; Crisci, M. (ION Publications (The Institute of navigation), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper discusses the unambiguous estimation of high-order BOC signals in the cloud based on signal snapshots gathered by low-end SDR receivers. In particular, the sensitivity and distortion problems are introduced, ...

    • Spatial-temporal processing with restriction of degrees of freedom for CDMA-multiuser detection 

      Muñoz Medina, Olga; Fernández Rubio, Juan Antonio (1998)
      Text en actes de congrés
      Accés obert
      Multipath distortion and multiple access interference are major limitations for the performance of wireless CDMA systems. In order to overcome both problems, a base-station antenna array RAKE receiver is proposed in this ...

    • Subset selection for multi-Gabor and non-orthogonal wavelets expansions 

      Rebollo-Neira, L; Fernández Rubio, Juan Antonio; Janer, L (IEEE Signal Processing Society, 1998)
      Text en actes de congrés
      Accés obert
      Non-orthogonal wavelets and Gabor or multi-windows Gabor expansions involving well-localized synthesis/analysis functions are characterized by being redundant. This entails that the signal modeling is carried out through ...

    • Tema 2: Tx Digital Canales AWGN 

      Cabrera-Bean, Margarita; Fernández Rubio, Juan Antonio; Riba Sagarra, Jaume (Universitat Politècnica de Catalunya, 2011)
      Problema, exercici
      Accés obert

    • Tema 5: Modulaciones avanzadas 

      Cabrera-Bean, Margarita; Fernández Rubio, Juan Antonio; Riba Sagarra, Jaume (Universitat Politècnica de Catalunya, 2008)
      Problema, exercici
      Accés obert

    • Temporal statistics of the beam-wander contribution to scintillation in ground-to-satellite optical links 

      Rodríguez Gómez, Alejandro Antonio; Dios Otín, Víctor Federico; Fernández Rubio, Juan Antonio; Comerón Tejero, Adolfo (2005-09-07)
      Article
      Accés obert
      The beam-wander contribution to the scintillation in a ground-to-satellite free-space optical link is one of major importance. An analytical model, based on the duality between beam wander and angle-of-arrival fluctuations, ...

    • The continuous wavelet transform as a maximum entropy solution of the corresponding inverse problem 

      Rebollo Neira, Laura; Fernández Rubio, Juan Antonio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-07-31)
      Article
      Accés obert
      The continuous wavelet transform is obtained as a maximum entropy solution of the corresponding inverse problem. It is well known that although a signal can be reconstructed from its wavelet transform, the expansion is ...

    • Time-delay estimation of the line-of-sight signal in a multipath environment 

      Seco Granados, Gonzalo; Fernández Rubio, Juan Antonio (EUSIPCO, 2000)
      Text en actes de congrés
      Accés obert
      The problem of estimating the time-delay of the line-of-sight (LOSS) or direct signal received by an antenna array in a multipath scenario is addressed. This problem is essential in many communication, radar, sonar and ...
