Erlang capacity degradation in multi-access/multi-service wireless networks due to terminal/coverage restrictions
Gelabert Doran, Xavier Bernardi; Sallent Roig, Oriol; Pérez Romero, Jordi; Agustí Comes, Ramon (2008)
Text en actes de congrés
Accés restringit per política de l'editorialThe benefits of jointly managing the combined radio resources offered by heterogeneous networks consisting of several Radio Access Technologies (RATs) have been profusely studied and assessed in recent years. Nevertheless, ... -
Exploiting the operating point in sensing-based opportunistic spectrum access scenarios
Gelabert Doran, Xavier Bernardi; Sallent Roig, Oriol; Pérez Romero, Jordi; Agustí Comes, Ramon (2009)
Comunicació de congrés
Accés obertSpectrum sensing is one key enabler towards opportunistic spectrum access in cognitive radio networks. Such scenarios allow cognitive users (a.k.a. secondary users) to access some licensed spectrum band as long as they do ... -
On the impact of multimode terminals in heterogeneous wireless access networks
Gelabert Doran, Xavier Bernardi; Pérez Romero, Jordi; Sallent Roig, Oriol; Agustí Comes, Ramon (IEEE, 2005)
Text en actes de congrés
Accés obertBeyond 3G (B3G) networks will encompass, among other features, a wide range of radio access technologies (RATs) providing users with a flexible and efficient access to the increasing pool of demanding services. This will ... -
Performance evaluation of radio access selection strategies in constrained multi-access/multi-service wireless networks
Gelabert Doran, Xavier Bernardi; Sallent Roig, Oriol; Pérez Romero, Jordi; Agustí Comes, Ramon (2011-01-07)

Spectrum sharing in cognitive radio networks with imperfect sensing: a discrete-time Markov model
Gelabert Doran, Xavier Bernardi; Sallent Roig, Oriol; Agustí Comes, Ramon; Pérez Romero, Jordi (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 ...
