    • Analog Transmission of Correlated Sources Over BC With Distortion Balancing 

      Suárez-Casal, Pedro; Fresnedo, Óscar; Castedo, Luis; Garcia-Frias, Javier (Institute of Electrical and Electronics Engineers, 2017-11)
      [Abstract]: Analog transmission of correlated information over Gaussian broadcast channels (BCs) using analog joint source- channel coding (JSCC) is addressed. This communication strategy has attractive advantages, such ...

    • Analog Transmission of Correlated Sources Over Fading SIMO Multiple Access Channels 

      Suárez-Casal, Pedro; Fresnedo, Óscar; Castedo, Luis; Garcia-Frias, Javier (Institute of Electrical and Electronics Engineers, 2017-07)
      [Abstract]: Joint source-channel coding for discrete-time analog sources is an appealing transmission approach because of its extremely low delay and complexity. When the users access the channel orthogonally, analog ...

    • Robust Precoding with Bayesian Error Modeling for Limited Feedback MU-MISO Systems 

      Joham, Michael; Castro-Castro, Paula-María; Castedo, Luis; Wolfgang, Utschick (IEEE, 2010)
      [Abstract] We consider the robust precoder design for multiuser multiple-input single-output (MU-MISO) systems where the channel state information (CSI) is fed back from the single antenna receivers to the centralized ...

    • Transmission of Spatio-Temporal Correlated Sources Over Fading Multiple Access Channels With DQLC Mappings 

      Fresnedo, Óscar; Suárez-Casal, Pedro; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2019-08)
      [Abstract]: The design of zero-delay Joint Source-Channel Coding (JSCC) schemes for the transmission of correlated information over fading Multiple Access Channels (MACs) is an interesting problem for many communication ...
