  • 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 ...
  • 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; 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
