  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Tauste Campo, Adrià; 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 ...
  • Vazquez-Vilar, Gonzalo; Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Two alternative exact characterizations of the minimum error probability of Bayesian M-ary hypothesis testing are derived. The first expression corresponds to the error probability of an induced binary hypothesis test and ...
  • Tauste Campo, Adrià; Principe, Alessandro; Ley Nacher, Miguel; Rocamora, Rodrigo; Deco, Gustavo (Public Library of Science (PLoS), 2018)
    Epileptic seizures are known to follow specific changes in brain dynamics. While some algorithms can nowadays robustly detect these changes, a clear understanding of the mechanism by which these alterations occur and ...
  • Vila-Vidal, Manel; Principe, Alessandro; Ley Nacher, Miguel; Deco, Gustavo; Tauste Campo, Adrià; Rocamora, Rodrigo (Elsevier, 2017)
    OBJECTIVE: We introduce a method that quantifies the consistent involvement of intracranially monitored regions in recurrent focal seizures. METHODS: We evaluated the consistency of two ictal spectral activation patterns ...
  • Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. Our main goal is to determine the performance loss caused by the need for estimating the ...
  • Leguia, Marc G.; Martínez, Cristina G. B.; Malvestio, Irene; Tauste Campo, Adrià; Rocamora, Rodrigo; Levnajić, Zoran; Andrzejak, Ralph Gregor (American Physical Society, 2019)
    Inferring the topology of a network using the knowledge of the signals of each of the interacting units is key to understanding real-world systems. One way to address this problem is using data- driven methods like ...
  • Leguia, Marc G; Martínez, Cristina G. B.; Malvestio, Irene; Tauste Campo, Adrià; Rocamora, Rodrigo; Levnajić, Zoran; Andrzejak, Ralph Gregor (Universitat Pompeu Fabra, 2019)
    In order to understand the source code of "Leguia MG, Martínez CGB, Malvestio I, Campo A T, Rocamora R, Levnajic Z, Andrzejak RG. 2019. Inferring directed networks using a rank-based connectivity measure. Phys. Rev. E. ...
  • 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 ...
  • Vila-Vidal, Manel; Pérez-Enríquez, Carmen; Principe, Alessandro; Rocamora, Rodrigo; Deco, Gustavo; Tauste Campo, Adrià (Elsevier, 2020)
    The spatial mapping of localized events in brain activity critically depends on the correct identification of the pattern signatures associated with those events. For instance, in the context of epilepsy research, a number ...
  • Bocharova, Irina E.; Guillén i Fàbregas, Albert; Kudryashov, Boris D.; Martinez, Alfonso; Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper studies an almost-lossless source-channel coding scheme in which source messages are assigned to different classes and encoded with a channel code that depends on the class index. The code performance is analyzed ...
  • Gilson, Matthieu; Tauste Campo, Adrià; Chen, X.; Thiele, Alexander; Deco, Gustavo (MIT Press, 2017)
    Directed connectivity inference has become a cornerstone in neuroscience to analyze multivariate data from neuroimaging and electrophysiological techniques. Here we propose a nonparametric significance method to test the ...
  • Sanchez-Larsen, Alvaro; Aznar Laín, Gemma; Benito Villabriga, Begoña; Principe, Alessandro; Ley Nacher, Miguel; Tauste Campo, Adrià; Rocamora, Rodrigo (Elsevier, 2017)
    Cardiac arrhythmias are a frequent complication related to seizures [1]. Most are benign although some, such as high-grade atrioventricular block, asystole, atrial fibrillation (AF), and ventricular fibrillation are ...
  • Gener, Thomas; Tauste Campo, Adrià; Alemany González, Maria, 1991-; Nebot Forcada, Pau; Delgado-Sallent, Cristina; Chanovas Colomé, Jordi; Puig Velasco, María Victoria (Elsevier, 2019)
    Atypical antipsychotic drugs (APDs) used to treat positive and negative symptoms in schizophrenia block serotonin receptors 5-HT2AR and dopamine receptors D2R and stimulate 5-HT1AR directly or indirectly. However, the exact ...
  • Tauste Campo, Adrià; Martínez-García, Marina; Nácher, Verónica; Luna, Rogelio; Romo, Ranulfo; Deco, Gustavo (National Academy of Sciences, 2015)
    Neural correlations during a cognitive task are central to study brain information processing and computation. However, they have been poorly analyzed due to the difficulty of recording simultaneous single neurons during ...
