Time-Varying Characteristics for V2V Channels in Complicated Scenarios

Wireless channel characterization and modeling is the foundation of vehicle-to-vehicle (V2V) communication systems. In this paper, the time-varying channel characteristics under three complicated scenes, namely, viaduct, tunnel and cutting, are measured and studied. Specifically, based on the targeted 5.9 GHz channel measurements, a detailed analysis of the time-varying power and delay of multipath components (MPCs) is presented. The research in this paper is helpful to the investigation of V2V channel propagation mechanism and the design of communication system.
