    • A novel formulation of independence detection based on the sample characteristic function 

      Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference lecture
      Open Access
      A novel independence test for continuous random sequences is proposed in this paper. The test is based on seeking for coherence in a particular fixed-dimension feature space based on a uniform sampling of the sample ...
    • A proof of de Bruijn identity based on generalized Price’s theorem 

      Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      This paper shows that de Bruijn identity, which relates entropy with Fisher information, can be obtained as a particular case of an immediate generalization of Price’s theorem, which is a tool used in the analysis of ...
    • Detection of dependence based on kernel signal processing 

      Cabrera Estanyol, Ferran de (Universitat Politècnica de Catalunya, 2017-02)
      Master thesis
      Open Access
    • Entropy-based covariance determinant estimation 

      Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference lecture
      Open Access
      An information-theoretic approach is described to estimate the determinant of the covariance matrix of a random vector sequence (a common task in a wide range of estimation and detection problems in signal processing for ...
    • Entropy-based non-data-aided SNR estimation 

      Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      A non-data-aided SNR estimation of a communication channel is addressed in this paper. The main contribution relies on the relationship between an entropy measure of a given constellation and the link quality. The main ...
    • Estimation of information in parallel Gaussian channels via model order selection 

      López Molina, Carlos Alejandro; Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference lecture
      Open Access
      We study the problem of estimating the overall mutual information in M independent parallel discrete-time memory-less Gaussian channels from N independent data sample pairs per channel (inputs and outputs). We focus on the ...
    • Multi-satellite cycle-slip detection and exclusion using the noise subspace of residual dynamics 

      Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de; Juan Zornoza, José Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      Real-time detection of cycle-slips on undifferenced carrier-phase measurements is an important task to properly exclude wrong phase trackers from precise positioning algorithms. The detection is especially challenging in ...
    • Robust estimation of the magnitude squared coherence based on Kernel signal processing 

      Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference lecture
      Open Access
      A new outlier-robust approach to estimate the magnitude squared coherence of a random vector sequence, a common task required in a variety of estimation and detection problems, is proposed. The proposed estimator is based ...
    • Sonda RF per al seguiment no-invasiu d'implants mèdics (stents) 

      Cabrera Estanyol, Ferran de (Universitat Politècnica de Catalunya, 2015-01)
      Bachelor thesis
      Restricted access - confidentiality agreement
    • Squared-loss mutual information via high-dimension coherence matrix estimation 

      Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      Squared-loss mutual information (SMI) is a surro- gate of Shannon mutual information that is more advantageous for estimation. On the other hand, the coherence matrix of a pair of random vectors, a power-normalized version ...
