Vehicle-to-Vehicle Channel Characteristics in Intersection Environment

Vehicular communication, as one of the most important supporting technologies of intelligent transportation system, has been widely concerned by academia and industry. Wireless channel characterization and modeling are the foundation of communication systems. Compared with typical road scenarios such as urban and suburban areas, wireless channel characterization in intersections is a challenging task. It is necessary to carry out measurement, characterization, and modeling for intersection channels as the basic theoretical support for vehicular communication system solutions. In this paper, channel measurements at 5.9 GHz in street intersection scenarios are carried out and provide data for the characterization and modeling of time-varying vehicular channels. Based on the measured data, this paper extracts and analyzes the time-varying power, delay and spatial characteristics and quantitatively models the influence of building obstruction on key channel parameters. The research in this paper can enrich the investigation of vehicular channels and enable the analysis and design of vehicular communication systems.
