    • Polar coding for the wiretap broadcast channel with multiple messages 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Comunicació de congrés
      Accés obert
      A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eaves-dropper. We consider a model in which the transmitter wishes to to reliably send different confidential and ...

    • Retrospective interference alignment for the MIMO interference broadcast channel 

      Torrellas, Marc; Agustín de Dios, Adrián; Vidal, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Retrospective Interference Alignment is a linear precoding strategy that seizes delayed channel state information at the transmitters (CSIT), improving the degrees of freedom (DoF) that can be achieved without CSIT for ...

    • Robust linear precoding for MSE minimization in MIMO broadcast systems with channel Gram matrix feedback 

      Sacristán Murga, Daniel; Payaró Llisterri, Miquel; Pascual Iserte, Antonio (IEEE, 2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper we deal with amultiple-input multiple-output (MIMO) multiuser broadcast channel (BC) featuring linear precoding at the transmitter. The design of such precoder is performed according to the channel state ...

    • The DoF of the 3-User (p, p+1) MIMO Interference Channel 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José; Muñoz Medina, Olga (2014-11-01)
      Article
      Accés restringit per política de l'editorial
      The degrees of freedom (DoF) of the 3-user multiple-input multiple-output (MIMO) interference channel (IC) with full channel state information and constant channel coefficients are investigated when (p, p + 1) antennas are ...
