  • Modeling 5G-NR-Based Positioning Accuracy in Urban Environments
    Publication

    - IEEE Access - Year 2025

    Modeling phenomena influencing radiocommunication networks, such as 5G-NR, is a key aspect during their development and further optimization. In this paper, one proposes a model, for three different scenario types in urban environments, for user localization accuracy. The model is supported by measurements of real 5G-NR downlink signals carried out in three different urban environments, corresponding to the typical user localization....

  • Trains Detection Using LTE Downlink Reference Signals

    In this article a method for detecting the presence of trains on tracks by analyzing the changes in the cell-specific reference symbols parameters in the downlink signal from nearby LTE base station operating in transmit diversity mode is proposed. The signal processing method to obtainwaveforms showing correlation with the presence of trains is described with experimental results on trains detection using real LTE downlink signals...
