  • 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 ...
  • Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    Our information technologies do not respond to the world's multicultural reality; in fact, we are imposing the paradigms of our market-driven western culture also on IT, thus facilitating the access of a small part of ...
  • Salamon, Justin; Gulati, Sankalp; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    The tonic is a fundamental concept in Indian classical music since it constitutes the base pitch from which a lead performer constructs the melodies, and accompanying instruments use it for tuning. This makes tonic ...
  • 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 ...
  • Serrà Julià, Joan; Koduri, Gopala Krishna; Miron, Marius; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The issue of tuning in Indian classical music has been, historically, a matter of theoretical debate. In this paper, we study its contemporary practice in sung performances of Carnatic and Hindustani music following an ...
  • 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 ...
  • Özaslan, Tan Hakan; Serra, Xavier; Arcos Rossell, Josep Lluís (International Society for Music Information Retrieval (ISMIR), 2012)
    The embellishments of makam music in Turkey are an inherent characteristic of the music rather than a separate expressive resource, thus their understanding is essential to characterize this music. We do a computational ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Intonation is an important concept in Carnatic music that is characteristic of a raaga, and intrinsic to the musical expression of a performer. In this paper we approach the description of intonation from a computational ...
