A Wideband Cluster-Based SCM Vehicle-toVehicle Channel Model in Roadside Scattering Environments

A novel cluster-based spatial channel model (SCM) for vehicle-to-vehicle (V2V) communications is proposed. This model is set up for V2V roadside scattering environments. To efficiently illustrate the real-world scenarios and describe non-stationary V2V channels, we divide all effective scatterers into three categories of clusters in terms of relative position of the scattering object. A mathematical expression of channel impulse response (CIR) is derived from an extension SCM and cluster-based models. Furthermore, the spatial and frequency statistical properties of the proposed V2V channel model are thoroughly studied. Finally, numerical simulations are presented to demonstrate the effectiveness of SCM V2V model.
