In this paper, we investigate the impact of mobile and stationary scattering clusters on the Doppler spectrum in wideband Vehicle-to-Vehicle (V2V) communication channels. The channel in which we simulate our model is an urban canyon oncoming environment. In the context of geometry-based stochastic channel models (GSCMs), we develop equal-delay contours for realistic modeling of location of both moving and stationary scatterers in vehicular environments. Then, we utilize our developed model to simulate the taps’ Doppler spectra. Numeric results demonstrate that the Doppler power spectra produced using the presented model is very close to the results obtained from measurements of V2V channels in an urban oncoming environment.
