A novel non-geometrical stochastic model (NGSM) for non-wide sense station-ary uncorrelated scattering (non-WSSUS) vehicle-to-vehicle (V2V) channels is proposed. This model is based on a conventional NGSM and employs a more accurate method to re-produce the realistic characteristics of V2V channels, which successfully extends the ex-isting NGSM to include the line-of-sight (LoS) component. Moreover, the statistical proper-ties of the proposed model in different scenarios, including Doppler power spectral density (PSD), power delay profile (PDP), and the tap correlation coefficient matrix are simulated and compared with those of the existing NGSM. Furthermore, the simulation results dem-onstrate not only the utility of the proposed model, but also the correctness of our theoreti-cal derivations.
