  • Variance processing for stable boundary-layer height estimation using backscatter lidar data: A discussion 

    Muñoz Porcar, Constantino; Silva, Marcos Paulo Araujo da; Saeed, Umar; Rey Micolau, Francesc; Pay Pérez, M. Teresa; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    In this paper we present a method for estimating the height of the nocturnal stable boundary layer by using lidar measurements and a single radiosonde for unambiguous initial guess. The method relies on the correlation ...
  • Floating Doppler Wind Lidar motion simulator for horizontal wind speed measurement error assessment 

    Salcedo Bosch, Andreu; Farré Guarné, Joan; Sala Álvarez, José; Villares Piera, Nemesio Javier; Tanamachi, Robin; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    This study presents a wind retrieval simulator of a floating Doppler Wind Lidar (DWL) with 6 Degrees of Freedom (DoF) motion. The simulator considers a continuous-wave conical-scanning floating DWL which retrieves the wind ...
  • Realistic beamforming design using SRS-based channel estimate for ns-3 5G-LENA module 

    Bojovic, Biljana; Lagén Morancho, Sandra; Giupponi, Lorenza (Association for Computing Machinery (ACM), 2021)
    Conference report
    Restricted access - publisher's policy
    Beamforming (BF) is a key procedure to overcome propagation limits in millimeter-wave bands but also to extend network coverage in sub 6 GHz bands, as considered in recent 3GPP and IEEE communication standards. Up to date, ...
  • Novel radio environment map for the ns-3 NR simulator 

    Koutlia, Katerina; Bojovic, Biljana; Lagén Morancho, Sandra; Giupponi, Lorenza (Association for Computing Machinery (ACM), 2021)
    Conference report

    Radio Environmental Map (REM) is a useful tool to visualize the network coverage, including signal quality and interference, in multi-cell scenarios. Although REM maps for omnidirectional transmissions/receptions and tools ...
  • An IR-HARQ scheme for covert communications 

    Lamarca Orozco, M. Meritxell (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    This paper explores the advantages of incremental redundancy hybrid-ARQ schemes for covert communications in which a feedback channel is available. The use of efficient incremental redundancy with sub-codewords of different ...
  • Energy-efficient analog beamforming with short packets in millimeter-wave MIMO systems 

    Borràs Pino, Jordi; Molina Oliveras, Francesc; López Valcarce, Roberto; Sala Álvarez, José (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    The energy-aware design of fully analog precoders and combiners is investigated in this paper. To that aim, we consider a millimeter-wave short-packet communication scenario where power consumption and hardware complexity ...
  • Rate allocation in massive multiple access combining successive decoding with error control 

    Molina Oliveras, Francesc; Sala Álvarez, José (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    The Gaussian multiple access channel under asymptotically many code-division-multiple-access users and successive interference cancellation (SIC) is investigated in this work. Users transmit n-symbol packets and select ...
  • 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 ...
  • 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 ...
  • Low-rank data matrix recovery with missing values and faulty sensors 

    Lopez Valcarce, Roberto; Sala Álvarez, José (2019)
    Conference lecture
    Open Access
    In practice, data gathered by wireless sensor networks often belongs in a low-dimensional subspace, but it can present missing as well as corrupted values due to sensor malfunctioning and/or malicious attacks. We study the ...
  • Polar coding for the wiretap broadcast channel with multiple messages 

    Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Open Access
    A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eaves-dropper. We consider a model in which the transmitter wishes to to reliably send different confidential and ...
  • Stochastic geometry analysis and design of wireless powered MTC networks 

    Liesegang Maria, Sergi; Muñoz Medina, Olga; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Machine-type-communications (MTC) are being crucial in the development of next generation mobile networks. Given that MTC devices are usually battery constrained, wireless power transfer (WPT) and energy harvesting (EH) ...
