Vehicular MMW Communication: Channel Characterization Based on Ray Tracing Study

Enabling future intelligent transportation systems heavily relies on Vehicle-to-Vehicle (V2V) communication with millimeter wave (MMW) communication emerging as a robust contender to facilitate V2V connectivity. In radio systems, radio channels are typically classified as multipath fading channels. Within the space between the transmitter and receiver, two primary signal propagation components exist: Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS). Channel modeling does not depend only on LOS, because the waves encounter various obstacles from roads, vehicles, trees and other objects. The channel impulse response serves as a widely utilized parameter for channel classification. Most of the earlier literature focuses on different parameters of MMW channels including received power, path loss, and delay spread. In an effort to better highlight the relative advantages of MMW channels, the impulse response of a multipath MMW channel can be characterized by using ray tracing tools in this paper.
