  • 60-GHz Millimeter-Wave Propagation Inside Bus: Measurement, Modeling, Simulation, and Performance Analysis 

    Chandra, Aniruddha; Ur Rahman, Aniq; Ghosh, Ushasi; García-Naya, José; Prokeš, Aleš; Blumenstein, Jiří; Mecklenbräuker, Christoph (IEEE, 2019-06-24)
    Millimeter-wave (mmWave) transmission over the unlicensed 60-GHz spectrum is a potential solution to realize high-speed internet access, even inside mass transit vehicles. The solution involves communication between users ...
  • Improved RMS Delay Spread Estimation for mmWave Channels Using Savitzky–Golay Filters 

    Miloš, Jiří; Blumenstein, Jiří; Prokeš, Aleš; Mikulášek, Tomáš; Mecklenbräuker, Christoph (MDPI, 2019-12-12)
    In this paper, a novel method for improving the estimation accuracy of the root mean square (RMS) delay spread from the magnitude of the Channel Transfer Function (CTF) is presented. We utilize the level crossing rate ...
  • In-vehicle channel sounding in the 5.8-GHz band 

    Kukolev, Pavel; Chandra, Aniruddha; Mikulášek, Tomáš; Prokeš, Aleš; Zemen, Thomas; Mecklenbräuker, Christoph (Springer, 2015-03-10)
    The article reports vehicular channel measurements in the frequency band of 5.8 GHz for IEEE 802.11p standard. Experiments for both intra-vehicle and out-of-vehicle environments were carried out. It was observed that the ...
  • Measurements of Ultra Wide Band In-vehicle channel - statistical description and TOA positioning feasibility study 

    Blumenstein, Jiří; Prokeš, Aleš; Mikulášek, Tomáš; Maršálek, Roman; Zemen, Thomas; Mecklenbräuker, Christoph (Springer, 2015-08-11)
    Článek popisuje výsledky měřící kampaně rádiového kanálu uvnitř osobního automobilu v pásmu 3-11 GHz. V článku je řešen efekt umístění antén a efekt přítomnosti pasažérů. Měření bylo provedeno ve frekvenční doméně a příslušné ...
  • Millimeter Wave Vehicular Channel Emulation: A Framework for Balancing Complexity and Accuracy 

    Blazek, Thomas; Zöchmann, Erich; Mecklenbräuker, Christoph (MDPI, 2018-11-16)
    We propose a general framework for the specification of a sparse representation of millimeter wave vehicular propagation channels and apply this to both synthetic data and real-world observations from channel sounding ...
  • Position-Specific Statistics of 60 GHz Vehicular Channels During Overtaking 

    Zöchmann, Erich; Hofer, Markus; Lerch, Martin; Pratschner, Stefan; Bernado, Laura; Blumenstein, Jiří; Caban, Sebastian; Sangodoyin, Seun; Groll, Herbert; Zemen, Thomas; Prokeš, Aleš; Rupp, Markus; Molisch, Andreas F.; Mecklenbräuker, Christoph (IEEE, 2019-01-15)
    The time-variant vehicle-to-vehicle radio propagation channel in the frequency band from 59.75 to 60.25 GHz has been measured in an urban street in the city center of Vienna, Austria. We have measured a set of 30 ...
