  • 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 from 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 way to demonstrate the usefulness of the methods we ...
  • Font, 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 ...
  • 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 very useful to have a proper linking between the ...
  • Escudero Mancebo, David; Hernández Leo, Davinia (2012)
    El trabajo presentado en esta comunicación se enmarca en un proyecto financiado por la Secretaría de Estado de Universidades, Ministerio de Educación Cultura y Deporte en su Programa de Estudios y Análisis, mejora de la ...
  • Hernández Leo, Davinia; Moreno, Verónica; Dimitriadis, Yannis; Asensio-Pérez, Juan I. (2010)
    Este trabajo recoge la experiencia llevada a cabo en tres asignaturas en cuanto a la aplicación de recomendaciones (acciones) dirigidas a la mejora de la alineación entre las competencias planteadas en los respectivos ...
  • 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 ...
  • Biglieri, Ezio (National Institute of Information and Communications Technology (NICT), 2008)
    We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel ...
  • Wang, Ni-Chun; Biglieri, Ezio; Yao, Kung (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    A systolic array to implement lattice-reduction-aided linear detection is proposed for a MIMO receiver. The lattice reduction algorithm 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 complete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • García Armada, Ana; Hong, Li; Lozano Solsona, Àngel (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 ...
  • Sridharan, Sriram; Lozano Solsona, Àngel; Viswanathan, Harish; Vishwanath, Sriram (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    This paper studies the fundamental operational limits of a class of Gaussian multicast channels with an interference setting. In particular, the paper considers two base stations multicasting separate messages to distinct ...
  • Krishna, T. M.; Ishwar, Vignesh (Universitat Pompeu Fabra, 2012)
    Over the last century in Karnatik music, the method of understanding raga has been to break it down into its various components, svara, scale, gamaka, and phrases. In this paper, an attempt is made to define the abstract ...
  • 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, Frederic; Roma, Gerard; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    There are many online communities with membergenerated and openly available multimedia content. Their success depends on having active contributing users and on producing useful content. With this criterion, the community ...
  • Vidwans, Amruta; Ganguli, Kaustuv Kanti; Rao, Preeti (Universitat Pompeu Fabra, 2012)
    A prominent categorization of Indian classical music is the Hindustani and Carnatic traditions, the two styles having evolved under distinctly different historical and cultural influences. Both styles are grounded in the ...
  • Giustiniano, Domenico; Gomà Llairo, Eduard; Morillo Pozo, Julián; López Toledo, Alberto; Rodríguez, Pablo (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    ADSL is becoming the standard form of residential and small-business broadband Internet access due to, primarily, its low deployment cost. These ADSL residential lines are often deployed with 802.11 Access Points (AP) that ...
  • Patrizini, Fabio; Lipovetzky, Nir; Giacomo, Giuseppe de; Geffner, Hector (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 ...
