  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We focus on full-rate, fast-decodable space–time block codes (STBCs) for 2 x 2 and 4 x 2 multiple-input multiple-output (MIMO) transmission. We first derive conditions and design criteria for reduced-complexity maximum-likelihood ...

  • Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The 2×2 MIMO profiles included in Mobile WiMAX specifications are Alamouti’s space-time code (STC) fortransmit diversity and spatial multiplexing (SM). The former has full diversity and the latter has full rate, but neither ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The problem of jointly estimating the number, the identities, and the data of active users in a time-varying multiuser environment was examined in a companion paper (IEEE Trans. Information Theory, vol. 53, no. 9, September ...
  • Hoogendoorn, Corné; Sukno, Federico M.; Ordás, Sebastián; Frangi Caregnato, Alejandro (Springer, 2009)
    In this work we describe the usage of bilinear statistical models as a means of factoring the shape variability into two components attributed to inter-subject variation and to the intrinsic dynamics of the human heart. ...
  • Faridi, Azadeh; Palattella, Maria Rita; Lozano Solsona, Àngel; Dohler, Mischa; Boggia, Gennaro; Grieco, Luigi Alfredo; Camarda, Pietro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 ...
  • Jindal, Nihar; Lozano Solsona, Àngel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user 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 ...
  • Boutros, Joseph Jean; Guillén i Fàbregas, Albert; Biglieri, Ezio; Zémor, Gilles (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    We design powerful low-density parity-check (LDPC) codes with iterative decoding for the block-fading channel. We first study the case of maximum-likelihood decoding, and show that the design criterion is rather straightforward. ...
  • Bogunovic, Hrvoje; Pozo Soler, José Ma. (José María); Villa-Uriol, Maria-Cruz; Majoie, Charles B. L. M.; van den Berg, Rene; Gratama van Andel, Hugo A. F.; Macho, Juan M.; Blasco, Jordi; San Román, Luis; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2010)
    Purpose: To evaluate the suitability of an improved version of an automatic segmentation method based on geodesic active regions (GAR) for segmenting cerebral vasculature with aneurysms from 3D X-ray reconstruc- tion ...
  • Villa-Uriol, Maria-Cruz; Larrabide, Ignacio; Pozo Soler, José Ma. (José María); Kim, Minsuok; Camara, Oscar; De Craene, Mathieu; Zhang, Chong; Geers, Arjan; Morales, Hernán; Bogunovic, Hrvoje; Cardenes, R.; Frangi Caregnato, Alejandro (Royal Society, 2010)
    In the last few years, some of the visionary concepts behind the virtual physiological human began to be demonstrated on various clinical domains, showing great promise for improving healthcare management. In the current ...
  • Lozano Solsona, Àngel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    In a MIMO layered architecture, several codewords are transmitted from a multiplicity of antennas. Although the spectral efficiency is maximized if the rates of these codewords are separately controlled, the feedback ...
  • Balocco, Simone; Basset, Olivier; Courbebaisse, Guy; Boni, Enrico; Frangi Caregnato, Alejandro; Tortoli, Piero; Cachard, Christian (Institute of Physics (IOP), 2010)
    Human arteries affected by atherosclerosis are characterized by altered wall viscoelastic properties. The possibility of noninvasively assessing arterial viscoelasticity in vivo would significantly contribute to the early ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens B.H.; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, G.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...
  • Oubel, E.; Cebral, J.R.; De Craene, Mathieu; Blanc, R.; Blasco, Jordi; Macho, Juan M.; Putman, C.M.; Frangi Caregnato, Alejandro (Institute of Physics (IOP), 2010)
    The quantification of wall motion in cerebral aneurysms is becoming important owing to its potential connection to rupture, and as a way to incorporate the effects of vascular compliance in computational fluid dynamics ...
  • Maestre Gómez, Esteban; Blaauw, Merlijn; Bonada, Jordi; Guaus, Enric; Pérez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Excitation-continuous music instrument control patterns are often not explicitly represented in current sound synthesis techniques when applied to automatic performance. Both physical model-based and sample-based synthesis ...
