英文摘要： Radio propagation and channel modeling for vehicle-to-vehicle wireless communication scenario is the basis for network design of vehicle-to-vehicle wireless communication. It is of great importance to the safety and efficiency of vehicular transportation. Based on realistic measurements, theoretical analysis, algorithm developments, modeling, and laboratory simulations, we conduct the in-depth research on the complex mechanism of multipath clustering, theories of time-variant channel measurement and parameter estimation, measure of multipath similarity in time-variant channel, multipath clustering theory and dynamic tracking algorithm of clustered multipath components, dynamic birth and death process of multipath clusters and cluster-based non-stationary channel modeling. Establishing a set of methods for vehicle-to-vehicle time-variant channel measurement, parameter estimation, multipath clustering, tracking, and modeling. Establishing simulation methods, which satisfies the clustering and non-stationarity characteristics of vehicle-to-vehicle time-variant channel, with low complexity and fast simulation speeds. With the in-depth investigations on the fundamental theory of radio propagation for vehicle-to-vehicle wireless communications, this project aims to establish multipath clustering theory of time-variant channel and the cluster-based multipath dynamic birth and death models, and make research achievements with independent intellectual property rights. It guides the engineering construction for vehicular communication systems, and guarantees the safety and high efficiency of vehicular transportations.
