Modeling of V2V Channels During Overtaking Maneuvers with Realistic 3D Mobility Patterns

This paper presents a new three-dimensional (3D) geometry-based statistical model (GBSM) of vehicle-to-vehicle (V2V) channels for the analysis of overtaking maneuvers. The 3D trajectories of the two vehicles involved in the maneuver are described by high-order polynomials. The coefficients of such polynomials are computed from real-world mobility patterns recorded in a measurement experiment conducted in a highspeed highway. The high-order polynomial trajectories allow a realistic characterization of the channel response at multiple observation time intervals from start to end of an overtaking. This differs from other GBSM for V2V channels in the state of the art, which consider linear or quadratic models that conform to rapidly changing mobility patterns only within a short-length window. Owing to its flexibility, the 3D GBSM of V2V channels presented in this paper can be used as a baseline for the design of V2V channel simulators with realistic mobility patterns.
