Abstract

This paper proposed a novel geometry-based 3D model for multiple-inputs and multiple-outputs(MIMO) vehicle-to-vehicle(V2V) communication system, which had the characteristics of multiple communication scenarios and moving transporter and receiver. This model combined the double sphere model and the semi-ellipsoid model for the first time and used the double sphere model and semi-ellipsoid model to represent dynamic and static scatterers respectively. Taking into account the movement state of the transporter and receiver, it introduced both time-varying angles and path lengths to study the non-stationary properties of V2V channel. For the proposed channel model, this paper derived the statistical characteristic functions such as spatial cross-correlation, temporal autocorrelation and Doppler power spectral density, and analyzed the statistical characteristics of the channel in different scenarios and parameters in depth. The observations and conclusions show that the various statistical properties of the V2V channel vary considerably in different scenarios, and the channel correlation is closely related to time variation and scatterer distribution. The height fitting between simulation results and the theoretical values verifies the correctness of the model. This paper provides a theoretical basis for the design of V2V communication links, and expands the research in the field of geometry-based V2V channel modeling.
