    Alonso-Zárate, Jesús; Kartsakli, Elli; Verikoukis, Christos; Alonso Zárate, Luis Gonzaga (HINDAWI, 2008-04-09)
    Article
    Open Access
    The persistent relay carrier sensing multiple access (PRCSMA) protocol is presented in this paper as a novel medium access control (MAC) protocol that allows for the execution of a distributed cooperative automatic ...
  • DVB-T signal detection for indoor environments in low-SNR regime 

    Kryszkiewicz, Pawel; Kliks, Adrian; Pérez Romero, Jordi; Umbert Juliana, Anna (2014-09-01)
    Article
    Open Access
    The problem of coexistence between the primary (licensed) and secondary (non-licensed) users can be solved in various ways. One of them assumes the application of the detailed Radio Environment Maps being a kind of ...
  • A rule-based solution search methodology for self-optimization in cellular networks

    With the advent of faster fourth-generation (4G) mobile broadband networks and the proliferation of a rich ecosystem of smartphone applications in the commercial domain, expectations and demand for much more sophisticated ...
  • Deployment and management of SDR cloud computing resources: problem definition and fundamental limits 

    Gómez Miguelez, Ismael; Marojevic, Vuk; Gelonch Bosch, Antonio José (2013-03)
    Article
    Open Access
    Software-defined radio (SDR) describes radio transceivers implemented in software that executes on general-purpose hardware. SDR combined with cloud computing technology will reshape the wireless access infrastructure, ...
  • Hybrid sparse linear array synthesis applied to phased antenna arrays 

    Yepes, Leonardo Fabio; Covarrubias, David; Alonso, Miguel A.; Ferrús Ferré, Ramón Antonio (2014-01-16)
    Article
    Restricted access - publisher's policy
    In this letter, a new hybrid technique to synthesize sparse linear arrays is proposed. This technique is based on the combination of two methods. As a first method, a deterministic synthesis algorithm is used to resolve ...
  • Spectrum usage in cognitive radio networks: from field measurements to empirical models 

    López Benítez, Miguel; Casadevall Palacio, Fernando José (2014-02)
    Article
    Restricted access - publisher's policy
    Cognitive Radio (CR) is aimed at increasing the e ffi ciency of spectrum utilization by allowing unlicensed users to access, in an op- portunistic and non-interfering manner, some licensed bands temporarily and / or ...
