    • Contribution to Dynamic Spectrum Assignment in multicell OFDMA networks 

      Bernardo Álvarez, Francisco (Universitat Politècnica de Catalunya, 2010-06-01)
      Tesi
      Accés obert
      La próxima cuarta generación (4G) de redes de comunicaciones móviles celulares considera una interfaz radio basada en OFDMA (Orthogonal Frequency Division Multiple Access). Esta tecnología ofrece robustez a la propagación ...

    • Distributed spectrum management based on reinforcement learning 

      Bernardo Álvarez, Francisco; Agustí Comes, Ramon; Pérez Romero, Jordi; Sallent Roig, Oriol (2009)
      Text en actes de congrés
      Accés obert
      This paper presents a novel distributed framework to decide the spectrum assignment in a primary cellular radio access network. The distributed nature of the framework allows each cell to autonomously decide (by means ...

    • Real-time HSPA emulator for end-to-edge QoS evaluation in all-IP beyond 3G heterogeneous wireless networks 

      López Benítez, Miguel; Bernardo Álvarez, Francisco; Vucevic, Nemanja; Umbert Juliana, Anna (ICST, 2008)
      Comunicació de congrés
      Accés obert
      This paper is aimed at presenting the real-time High Speed Packet Access (HSPA) emulator that has been developed in the framework of the AROMA project. Real-time emula- tors allow reproducing realistic scenarios to test ...

    • Temporal and spatial spectrum assignment in next generation OFDMA networks through reinforcement learning 

      Bernardo Álvarez, Francisco; Agustí Comes, Ramon; Pérez Romero, Jordi; Sallent Roig, Oriol (2009)
      Text en actes de congrés
      Accés obert
      This paper proposes a Dynamic Spectrum Assignment strategy in the context of next generation multicell Orthogonal Frequency Division Multiple Access networks. The proposed strategy is able to dynamically find spectrum ...
