    Clusters of SMPs are ubiquitous. They have been traditionally programmed by using MPI. But, the productivity of MPI programmers is low because of the complexity of expressing parallelism and communication, and the difficulty ...

  • Joint pilot and precoder design for optimal throughput 

    Pastore, Adriano; Joham, Michael; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    For single-user, multiple-input multiple-output (MIMO) channels with Rayleigh fading correlated at the transmitter side, and where the receiver only has partial channel knowledge in form of an MMSE channel estimate, we ...

  • Multiantenna GLR detection of rank-one signals with known power spectrum in white noise with unknown spatial correlation 

    Sala Álvarez, José; Vázquez Vilar, Gonzalo; López Valcarce, Roberto (2012-06)
    Article
    Accés restringit per política de l'editorial
    Multiple-antenna detection of a Gaussian signal with spatial rank one in temporally white Gaussian noise with arbitrary and unknown spatial covariance is considered. This is motivated by spectrum sensing problems in the ...

  • On the ability of adaptation of speech signals and data hiding 

    Ballesteros, D.M.L.; Moreno Aróstegui, Juan Manuel (2012-11-15)
    Article
    Accés restringit per política de l'editorial
    The efficient wavelet masking is a scheme of speech-in-speech hiding based on the ability of adaptation of speech signals under the hypothesis “any (speech) secret signal may seem similar to a (speech) host signal if its ...

  • Electro-thermal coupling analysis methodology for RF circuits 

    Gómez Salinas, Didac; Dufis, Cédric Yvan; Altet Sanahujes, Josep; Mateo Peña, Diego; González Jiménez, José Luis (2012-09)
    Article
    Accés restringit per política de l'editorial
    In this paper an electro-thermal co-simulation methodology suitable for RF circuits is presented. It circumvents traditional transient simulation drawbacks that arise when signals or magnitudes whose frequencies are separated ...

  • Track detection in railway sidings based on MEMS gyroscope sensors 

    Broquetas Ibars, Antoni; Comerón Tejero, Adolfo; Gelonch Bosch, Antonio José; Fuertes Armengol, José Mª; Castro Fernández, José Antonio; Felip, Damià; López Márquez, Miguel Ángel; Pulido, Jose Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2012-11-23)
    Article
    Accés obert
    The paper presents a two-step technique for real-time track detection in single-track railway sidings using low-cost MEMS gyroscopes. The objective is to reliably know the path the train has taken in a switch, diverted or ...
