  • Remote monitoring of Markov sources over random access channels: false alarm and detection probability 

    Munari, Andrea; Cocco, Giuseppe; Liva, Gianluigi (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    We study the problem of remote source monitoring in an Internet of Things (IoT) system where a set of devices share a wireless channel to a common receiver. Each device observes an independent two-state Markov chain, with ...
  • State estimation entropy for two-state markov sources in slotted ALOHA random access channels 

    Cocco, Giuseppe; Munari, Andrea; Liva, Gianluigi (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Restricted access - confidentiality agreement
    We study a system in which terminals monitoring two-state Markov sources communicate towards a common receiver over a slotted ALOHA random access channel. We analyze the system performance in terms of state estimation ...
  • Reconfigurable intelligent surfaces for receive spatial modulation in rank-deficient channels 

    Moreno Locubiche, Ainna Yue; Vidal Manzano, José; Pascual Iserte, Antonio; Muñoz Medina, Olga (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    Receive spatial modulation (RSM) has been proposed as an effective transmission technology for next-generation wireless communications systems because of its reduced complexity and low energy consumption at the receiver ...
  • Contextual multi-armed bandits for non-stationary wireless network selection 

    Martínez Casanovas, Lluís; Vidal Manzano, José; Cabrera-Bean, Margarita (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    As the number of wireless technologies (4G, 5G, 802.11ax and other) have been rapidly increasing, so have the number of wireless networks concurrently deployed on a given coverage area. As a result, the judicious selection ...
  • A survey of 5G-based positioning for industry 4.0: state of the art and enhanced techniques 

    Muthineni, Karthik; Artemenko, Alexander; Vidal Manzano, José; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
    Open Access
    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)
    Conference lecture
    Open Access
    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)
    Conference report
    Open Access
    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)
    Conference lecture
    Open Access
    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)
    Conference lecture
    Open Access
    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)
    Conference report
    Open Access
    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)
    Conference lecture
    Open Access
    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)
    Conference report
    Open Access
    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 ...
