  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper presents our investigation on iterative/ndecoding performances of some sparse-graph codes on block-fading Rayleigh channels. The considered code ensembles are standard LDPC codes and Root-LDPC codes, first ...
  • Farrús, Mireia; Garde, Ainara; Ejarque, Pascual; Luque, Jordi; Hernando, Javier (International Speech Communication Association (ISCA), 2006)
    Comunicació presentada a: 9th International Conference on Spoken Language Processing; 17-21 de setembre de 2006 a Pittsburgh, Estats Units d'Amèrica
  • Dzhambazov, Georgi Bogomilov; Srinivasamurthy, Ajay; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    Lyrics-to-audio alignment aims to automatically match given lyrics and musical audio. In this work we extend a state of the art approach for lyrics-to-audio alignment with information about note onsets. In particular, ...
  • Marichal, Sebastián; Malaisé, Adrien; Modugno, Valerio; Dermy, Oriane; Charpillet, François; Ivaldi, Serena (Springer, 2016)
    In this paper we study the relation between the performance of use and user preferences for a robotic arm control interface. We are interested in the user preference of non-experts after a one-shot evaluation of the ...
  • Meditskos, Georgios; Kontopoulos, Efstratios; Vrochidis, Stefanos; Kompatsiaris, Ioannis (CEUR Workshop Proceedings (CEUR-WS.org), 2016)
    In this paper we present a framework for conversational awareness and conflict resolution in spoken dialogue systems for home care assistance. Conver-sational awareness is supported through OWL ontologies for capturing ...
  • Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The current research in Music Information Retrieval (MIR) is showing the potential that the Information Technologies can have in music related applications. A/nmajor research challenge in that direction is how to ...
  • Cyriac, Praveen; Kane, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    The sensor values captured by a digital camera are transformed in a non-linear manner prior to quantization in order to make the quantization rate approximately proportional to the sensitivity of the human visual system. ...
  • George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper addresses the benefits of introducing exclusion regions around both transmitters and receivers in D2D wireless networks. Such exclusion regions offer protection from interference at the expense of a sparser ...
  • Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in 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 quantified. The ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper derives approximations allowing the estimation of outage probability for standard irregular LDPC codes and full-diversity Root-LDPC codes used over nonergodic block-fading channels. Two separate approaches are ...
  • Farrús, Mireia; Lai, Catherine; Moore, Johanna D. (International Speech Communication Association, 2016)
    Speech synthesis has improved in both expressiveness and voice quality in recent years. However, obtaining full expressiveness when dealing with large multi-sentential synthesized discourse is still a challenge, since ...
  • Smith, Julius O.; Serra, Xavier (International Computer Music Conference, 1987)
    This paper describes a peak-tracking spectrum analyzer, called PARSHL, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano. PARSHL is based on the Short-Time Fourier Transform ...
  • Cyriac, Praveen; Kane, David; Bertalmío, Marcelo (The British Machine Vision Association (BMVA), 2015)
    Digital cameras apply a non-linearity to the captured sensor values prior to quantisation. This process is known as perceptual linearisation and ensures that the quantisation rate is approximately proportional to human ...
  • Bertalmío, Marcelo; Vazquez-Corral, Javier (Color Science Association of Japan (CSAJ), 2015)
    Gamut mapping transforms the color of an input image within the range of a target device. A huge amount of research has been devoted to two subproblems that arise from this general one: gamut reduction and gamut extension. ...
  • Moreno, Verónica; Bellalta, Boris; Infante, Jorge; Piella Fenoy, Gemma; Frangi Caregnato, Alejandro (2009-07-03)
    L’Escola Superior Politècnica (ESUP) de la Universitat Pompeu Fabra (UPF) ha realitzat una anàlisi per conèixer el perfil dels estudiants que s’incorporen a les Enginyeries de Telecomunicacions i Informàtica contemplant ...
  • Mungara, Ratheesh K.; Zhang, Xinchen; Lozano Solsona, Angel; Heath, R. W., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    We present a performance evaluation of ITLinQ/nand FlashLinQ, the two most popular schemes proposed to date/nto channelize D2D transmissions, i.e., to parse transmissions/ninto noninterfering sets to be allocated to separate ...
