Enabling Vehicular mmWave Communication Links Using cmWave Information
Future connected cooperative automated mobility can benefit from high-data-rate wireless communication links between vehicles to exchange LIDAR and/or RADAR data. The millimeter wave (mmWave) frequency range offers large bandwidth for rapid sensor data exchange but suffers from higher signal attenuation compared to the centimeter wave (cmWave) band. In this paper we obtain cmWave and mmWave multipath component (MPC) parameters by combining a single omnidirectional antenna that is used as virtual array with the CLEAN algorithm. The cmWave MPC information enables low-overhead mmWave beamforming by means of an antenna array. Empirical multi-band measurement data (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$3.2 \text{GHz}, 34.3 \text{GHz}$</tex>, and 62.35 GHz) shows that considering the 5 strongest MPCs, a signal-to-noise ratio of up to 25 dB for a V2I scenario can be achieved.
