  • 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 ...
  • 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 ...
  • 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 ...
  • Font Corbera, Frederic; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    User generated content shared in online communities is often described using collaborative tagging systems where users assign labels to content resources. As a result, a folksonomy emerges that relates a number of tags ...
  • 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 ...
  • García Armada, Ana; Hong, Li; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    For single-user MIMO communication with uncoded and coded QAM signals, we propose bit and power loading schemes that rely only on channel distribution information at the transmitter. To that end, we develop the relationship ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance ...
  • Font Corbera, Frederic; Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    There are many online communities with membergenerated and openly available multimedia content. Their success/ndepends on having active contributing users and on producing useful content. With this criterion, the community ...
  • Patrizini, Fabio; Lipovetzky, Nir; Giacomo, Giuseppe de; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Classical planning has been notably successful in synthesizing finite plans to achieve states where propositional goals hold. In the last few years, classical planning has also been extended to incorporate temporally ...
  • Meinhardt Llopis, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We propose an edge detector based on the selection of well/ncontrasted pieces of level lines, following the proposal of/nDesolneux-Moisan-Morel (DMM) [1]. The DMM edge detector/nhas the problem of over-representation, that ...
  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We show how to build full-diversity product codes under both iterative encoding and decoding over non-ergodic channels, in presence of block erasure and block fading. The concept of a rootcheck or a root subcode is introduced ...
  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    A new graph-based construction of generalized low density codes (GLD-Tanner) with binary BCH constituents is described. The proposed family of GLD codes is optimal on block erasure channels and quasi-optimal on block fading ...
  • Maestre Gómez, Esteban; Pérez Carrillo, Alfonso Antonio, 1977-; Ramírez, Rafael,1966- (International Computer Music Association, 2010)
    This paper presents a framework in which samples of bowing gesture parameters are retrieved and concatenated from a database of violin performances by attending to an annotated input score. Resulting bowing parameter signals ...
  • Ramírez Jávega, Miquel; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Plan recognition is the problem of inferring the goals and plans of an agent from partial observations of her behavior. Recently, it has been shown that the problem can be formulated and solved using/nplanners, reducing ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (European Association for Signal Processing (EURASIP), 2008)
    This paper presents several algorithms for joint estimation of the target number and state in a time-varying scenario. Building on the results presented in [1], which considers estimation of the target number only, we ...
