  • Persistent RCSMA: a MAC protocol for a distributed cooperative ARQ scheme in wireless networks 

    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 ...
  • Intercell interference coordination for control channels in LTE and LTE-A: an optimization scheme based on evolutionary algorithms 

    González González, David; García Lozano, Mario; Ruiz Boqué, Sílvia (2014-12-18)
    Article
    Restricted access - publisher's policy
    Intercell Interference Coordination (ICIC) encompasses techniques aiming at reducing the intercell interference at cell edges, an issue affecting not only data but also control channels in Long Term Evolution (LTE) and ...
  • Superregenerative reception of narrowband FSK modulations 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; López Riera, Alexis; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2015-03-01)
    Article
    Open Access
    In this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different ...
  • Twisted toroidal vortex solitons in inhomogeneous media with repulsive nonlinearity 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Shnir, Yasha; Torner Sabata, Lluís (2014-12-24)
    Article
    Open Access
    Toroidal modes in the form of so-called Hopfions, with two independent winding numbers, a hidden one (twist s), which characterizes a circular vortex thread embedded into a three-dimensional soliton, and the vorticity ...
  • CEMS and Faraday rotation study of gamma-Fe2O3-Fe3O4 films obtained by a new pyrolisis technique 

    Cusidó Fàbregas, Joan Antoni; Obradors, Xavier; Fontcuberta, Josep; Isalgue Buxeda, Antonio; Canal Bienzobas, Fernando (1987-01-10)

  • Fast super-resolution via dense local training and inverse regressor search 

    Pérez-Pellitero, Eduardo; Salvador, Jordi; Torres-Xirau, Iban; Ruiz Hidalgo, Javier; Rosenhahn, Bodo (2014-11-01)
    Article
    Restricted access - publisher's policy
    Regression-based Super-Resolution (SR) addresses the upscaling problem by learning a mapping function (i.e. regressor) from the low-resolution to the high-resolution manifold. Under the locally linear assumption, this ...
  • Tourism demand forecasting with neural network models: different ways of treating information 

    Claveria, Oscar; Monte Moreno, Enrique; Torra Porras, Salvador (John Wiley & Sons, 2014-07-21)
    Article
    Restricted access - publisher's policy
    This paper aims to compare the performance of three different artificial neural network techniques for tourist demand forecasting: a multi-layer perceptron, a radial basis function and an Elman network. We find that ...
  • Advanced radar geosynchronous observation system: ARGOS 

    Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Recchia, Andrea; Rocca, Fabio; Ruiz Rodon, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015-07-01)
    Article
    Open Access
    The Advanced Radar Geosynchronous Observation System is proposed to be a multiple-input–multiple-output synthetic aperture radar (SAR) system hosted on a swarm of minisatellites in quasi-geostationary orbits. The system ...
  • Stochastic estimation of the Frobenius norm in the ACA convergence criterion 

    Heldring, Alexander; Úbeda Farré, Eduard; Rius Casals, Juan Manuel (2015-03-01)
    Article
    Open Access
    The adaptive cross approximation (ACA) algorithm has been used in many fast Integral Equation solvers for electromagnetic Radiation and Scattering problems. It efficiently computes a low rank approximation to the interaction ...
  • Global impostor selection for DBNs in multi-session i-vector speaker recognition 

    Ghahabi Esfahani, Omid; Hernando Pericás, Francisco Javier (2014-11-19)
    Article
    Restricted access - publisher's policy
    An effective global impostor selection method is proposed in this paper for discriminative Deep Belief Networks (DBN) in the context of a multi-session i-vector based speaker recognition. The proposed method is an ...
