      Text en actes de congrés
      Accés obert
      The fifth generation (5G) mobile communication technology integrates communication, positioning, and mapping functionalities as an in-built feature. This has drawn significant attention from industries owing to the capability ...
    • Correlation study between the performance in different engineering courses and project-based courses 

      Bermejo Broto, Sandra; Bragós Bardia, Ramon; Rey Micolau, Francesc; Pegueroles Vallés, Josep R. (NTNU SEED, 2023)
      Comunicació de congrés
      Accés obert
      In a previous study, already published (Bragós, 2022), we analyzed the correlation between the University access mark to the engineering studies with the grades obtained in projectbased courses and in non-project-based ...
    • Higher-order link prediction via learnable maximum mean discrepancy 

      Karanikolas, Georgios V.; Pagès Zamora, Alba Maria; Giannakis, Georgios B. (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Text en actes de congrés
      Accés obert
      Higher-order link prediction (HOLP) seeks missing links capturing dependencies among three or more network nodes. Predicting high-order links (HOLs) can for instance reveal hyperlinks in the structure of drug substance and ...
    • Data driven joint sensor fusion and regression based on geometric mean squared error 

      López Molina, Carlos Alejandro; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Comunicació de congrés
      Accés obert
      This paper explores the problem of estimating a temporal series measured from multiple independent sensors with unequal and stationary measurement errors with unknown variances. By formulating the data fusion problem as a ...
    • Base station on/off strategies for wireless networks powered with energy harvesting sources 

      Rubio López, Javier; Pascual Iserte, Antonio; Vidal Manzano, José (2015)
      Comunicació de congrés
      Accés obert
      In this paper, we present a procedure for switching on and off base stations (BSs) that are powered with solar panels and have finite batteries. In the scenario under consideration it is considered that the BSs are placed ...
    • Sparse-aware approach for covariance conversion in FDD systems 

      López Molina, Carlos Alejandro; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Text en actes de congrés
      Accés obert
      This paper proposes a practical way to solve the Uplink-Downlink Covariance Conversion (UDCC) problem in a Frequency Division Duplex (FDD) communication system. The UDCC problem consists in the estimation of the Downlink ...
    • 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 ...
    • Energy driven transmission schemes for coexistence between HTC and MTC 

      Liesegang Maria, Sergi; Pascual Iserte, Antonio; Muñoz Medina, Olga (VDE Verlag, 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Coexistence between human-type and machine-type communications is essential in future cellular networks. The former demands high data rates whereas long battery lifetimes are crucial for the latter. In this paper, we ...
    • Hierarchical beamforming in random access channels 

      Agustín de Dios, Adrián; Cabrera-Bean, Margarita; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Comunicació de congrés
      Accés obert
      Managing a massive number of terminals in a contention-based multiple access is challenging due to its intrinsic limited efficiency. For example, in the random access channel considered in LTE-A and 5G NR, Base Station ...
