      Casadevall Palacio, Fernando José; Agustí Comes, Ramon; Pérez Romero, Jordi; López Benítez, Miguel; Grimoud, Sebastien; Sayrac, Berna; Dagres, Ioannis; Polydoros, Andreas; Riihijärvi, Janne; Nasreddine, Jad Nayef; Mähönen, Petri; Gavrilovska, Liljana; Atanasovski, Vladimir; van de Beek, Jaap (2011-04-30)
      Report de recerca
      Accés obert
      We describe herein the envisioned improvements of the REMs due to advanced sensing and processing. In relation to that, we also discuss the underlying modelling assumptions. Finally, we comment on how REMs can be of use ...
    • Reinforcement learning for load management in DiffServ-MPLS mobile networks 

      Vucevic, Nemanja; Pérez Romero, Jordi; Sallent Roig, Oriol; Agustí Comes, Ramon (2009)
      Text en actes de congrés
      Accés obert
      Cognitive networks are envisaged to provide optimized resource usage in future. While heterogeneity and resource scarcity draw research attention to the wireless part, the rest of the network (mobile backhaul) is rarely ...
    • Resource Management in Multicarrier Based Cognitive Radio Systems 

      Shaat, Musbah M. R. (Universitat Politècnica de Catalunya, 2012-03-09)
      Tesi
      Accés obert
      The ever-increasing growth of the wireless application and services affirms the importance of the effective usage of the limited radio spectrum. Existing spectrum management policies have led to significant spectrum ...

      Article
      Accés restringit per política de l'editorial
      An efficient and utmost utilization of currently scarce and underutilized radio spectrum resources has stimulated the introduction of what has been coined Cognitive Radio (CR) access methodologies and implementations. While ...
    • Study of admission and control system in a centralized cognitive radio network for heterogeneous wireless frequency devices 

      Torró Vilert, Albert (Universitat Politècnica de Catalunya, 2011-05-25)
      Projecte Final de Màster Oficial
      Accés obert
      This project focuses on the Cognitive Radio Technology initially proposed by Joseph Mitola at the end of 90s. The concept of Cognitive Radio introduces the idea that nowadays telecommunications systems must be aware of the ...
