    • A novel methodology for adaptive community detection 

      Vila Insa, Marc (Universitat Politècnica de Catalunya, 2019-06)
      Treball Final de Grau
      Accés obert
      Community detection and statistical dependence detection between different sets of data are two very intertwined topics of research with many real world applications in areas involving information science resources, such ...

    • A test for conditional correlation between random vectors based on weighted u-statistics 

      Vila Insa, Marc; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Comunicació de congrés
      Accés obert
      This article explores U-Statistics as a tool for testing conditional correlation between two multivariate sources with respect to a potential confounder. The proposed approach is effectively an instance of weighted ...

    • Affine projection subspace tracking 

      Vila Insa, Marc; López Molina, Carlos Alejandro; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Comunicació de congrés
      Accés obert
      In this paper, we consider the problem of estimating and tracking an R-dimensional subspace with relevant information embedded in an N-dimensional ambient space, given that N>>R. We focus on a formulation of the signal ...

    • Compression of multibeam echosounders bathymetry and water column data 

      Martí, Aniol; Portell de Mora, Jordi; Amblàs Novellas, David; Cabrera Estanyol, Ferran de; Vila Insa, Marc; Riba Sagarra, Jaume; Mitchell, Garrett (Multidisciplinary Digital Publishing Institute (MDPI), 2022-04-25)
      Article
      Accés obert
      Over the past decade, Multibeam Echosounders (MBES) have become one of the most used techniques in sea exploration. Modern MBES are capable of acquiring both bathymetric information on the seafloor and the reflectivity of ...

    • Lens antenna arrays: an efficient framework for sparse-aware large-MIMO communications 

      Vila Insa, Marc (Universitat Politècnica de Catalunya, 2021-06)
      Projecte Final de Màster Oficial
      Accés obert
      The recent increase in the demand for higher data transmission rates in wireless communications has entailed many implementation issues that can only be resolved by going through a full paradigm shift. Making use of the ...

    • On infinite past predictability of cyclostationary signals 

      Riba Sagarra, Jaume; Vila Insa, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Article
      Accés obert
      This paper explores the asymptotic spectral decomposition of periodically Toeplitz matrices with finite summable elements. As an alternative to polyphase decomposition and other approaches based on Gladyshev representation, ...
