Spectral Leakage Reduction of Power-Delay-Doppler Profile for mm-Wave V2I Channel
Vehicle-to-everything communications using mil-limeter wave has come into the spotlight with autonomous vehicles. Due to high speed of antennas or scatterers, spectral leakage of Doppler spectrum easily occurs in vehicular channel environments. In this paper, the algorithm to reduce spectral leakage is proposed. The main idea is searching for the frequency of the peak power component and shifting sampling frequencies. Doppler measurement results at 28 GHz in a vehicular-to-infrastructure environment are also shown.
