Study of Path Loss Models in V2V mm-Wave Communication

Recent research has focused on millimeter wave (mmWave) bands as a way to improve automated driving and meet the demanding data rate and latency requirements of developing automotive applications. Accurate channel models that can predict the uniqueness of vehicular propagation at these bands, particularly about Vehicle-to-Vehicle (V2V) communications, are required for the development of such systems to operate in bands over 6 GHz. In this paper, we have validated the proposed mmWave path loss models for the NR-V2X system with the help of link-level simulation. Here bit error rate (BER) performance of three path loss models has been compared by varying inter-vehicular distance (IVD). We also observe the effect of different modulation schemes on the BER curve for a fixed path loss model and proposed the best-suited modulation technique for the mm-wave V2X system.
