    • Net DoF analysis for the K-user MISO IC with outdated and imperfect channel feedback 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The net degrees of freedom (DoF ) describe the efficiency of a protocol in terms of network throughput at high signal-to-noise ratio (SNR). As the conventional DoF, it captures how the achievable user data rate grows as ...

    • On the degrees of freedom of the K-user MISO interference channel with imperfect delayed CSIT 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work investigates the degrees of freedom (DoF) of the K-user multiple-input single-output (MISO) interference channel (IC) with imperfect delayed channel state information at the transmitters (dCSIT). For this setting, ...

    • Performance analysis of inter-cell interference coordination in small-cell networks with long feedback delays 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Current state-of-the-art approaches are evaluated for the downlink (DL) of an LTE-based wireless network when multiple Small-Cells (SC) eNBs coexist in the same area. With the aim of increasing data-rate performance of ...

    • Retrospective interference alignment for the 3-user MIMO interference channel with delayed CSIT 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The degrees of freedom (DoF) of the 3-user multiple input multiple output interference channel (3-user MIMO IC) are investigated where there is delayed channel state information at the transmitters (dCSIT). We generalize ...

    • The Degrees of Freedom of the 3-user (p,p+1) MIMO Interference channel 

      Torrellas Socastro, Marc (Universitat Politècnica de Catalunya, 2013-06-25)
      Projecte Final de Màster Oficial
      Accés obert
      [ANGLÈS] This work is focused on the study of the fundamental limits of wireless channels. In this context, the degrees of freedom (DoF) are a measure to analyze those limits at the high SNR regime. The contribution of ...

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