Radio environmental maps: information models and reference model. Document number D4.1
(2011-04-30)
Report de recerca
Accés obertWe 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
(2009)
Text en actes de congrés
Accés obertCognitive 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
(Universitat Politècnica de Catalunya, 2012-03-09)
Tesi
Accés obertThe 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 ... -

Spectrum sharing in cognitive radio networks with imperfect sensing: a discrete-time Markov model
(2010-10)
Article
Accés restringit per política de l'editorialAn 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
(Universitat Politècnica de Catalunya, 2011-05-25)
Projecte Final de Màster Oficial
Accés obertThis 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 ...
