  • Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    Multiple-input multiple-output (MIMO) techniques have become an essential part of broadband wireless communications systems. For example, the recently developed IEEE 802.16e specifications for broadband wireless access ...
  • Pérez Sanagustín, Maria del Mar; Santos Rodríguez, Patrícia; Moghnie, Ayman; Hernández Leo, Davinia; Blat, Josep (Inderscience Enterprises Ltd, 2009)
    The emergence of the Web 2.0 technologies in the last years have/nchanged the way people interact with knowledge. Services for cooperation and/ncollaboration have placed the user in the centre of a new knowledge building/nspace. ...
  • Bellur, Ashwin; Ishwar, Vignesh; Serra, Xavier; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper a method for extracting semantic information/nfrom online music discussion forums is proposed. The semantic relations are inferred from the co-occurrence of musical concepts in forum posts, using network ...
  • Sordo, Mohamed; Koduri, Gopala Krishna; Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In the context of the CompMusic project we are developing methods to automatically describe/annotate audio music recordings pertaining to various music cultures. As a/nway to demonstrate the usefulness of the methods we ...
  • Wang, Ni-Chun; Biglieri, Ezio; Yao, Kung (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    A systolic array to implement lattice-reduction-aided linear/ndetection is proposed for a MIMO receiver. The lattice reduction/nalgorithm and the ensuing linear detections are operated in the same array, which can be ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a/ncomplete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is ...
  • Venkatesan, Sivarama; Huang, Howard C.; Lozano Solsona, Angel; Valenzuela, R. A. (Hindawi, 2009)
    It is well known that multiple-input multiple-output (MIMO) techniques can bring numerous benefits, such as higher spectral efficiency, to point-to-point wireless links. More recently, there has been interest in extending ...
  • Ferradans Ramonde, Sira; Bertalmío, Marcelo; Provenzi, Edoardo; Caselles, Vicente (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Tone Mapping is the problem of compressing the range of a High-Dynamic Range image so that it can be displayed in a Low-Dynamic Range screen, without losing or introducing novel details: The final image should produce in ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The main information sources to study a particular piece of music are symbolic scores and audio recordings. These are complementary representations of the piece and it is/nvery useful to have a proper linking between the ...
  • Sarala, Padi; Ishwar, Vignesh; Bellur, Ashwin; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    A Carnatic music concert is made up of a sequence of pieces, where each piece corresponds to a particular genre and ra¯aga (melody). Unlike a western music concert, the artist may be applauded intra-performance ...
  • Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Ungureanu, Camil (Centre d'Informació i Documentació Internacionals a Barcelona (CIDOB)Grup de Recerca Interdisciplinari sobre Immigració (GRITIM-UPF), 2011)
    How is it possible to square the development of a consistent European/napproach to religious diversity with the recognition of the sometimes-conflictive/nplurality of state-religion models? The Court´s support of the ...

  • Cabo Rigol, Mercè; Espinós Ferrer, Montserrat (Centro Latinoamericano de Administración para el Desarrollo, 2004)
    La Universitat Pompeu Fabra, después de una fase de revisión y análisis de sus estructuras, inició a finales del año 2003 una reestructuración organizativa. Esta reestructuración se inscribe en un marco más amplio de medidas ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    We characterize the capacity-achieving input covariance for multi-antenna channels known instantaneously at the receiver and in distribution at the transmitter. Our characterization, valid for arbitrary numbers of antennas, ...
  • Huguet, Marina; Tobón Gómez, Catalina, 1981-; Bijnens, Bart; Frangi Caregnato, Alejandro; Petit i Guinovart, Màrius (BioMed Central, 2009)
