Enhancing the Non-Geometric Stochastic Model for Vehicle-to- Vehicle Channels Outside of the WSSUS

Abstract

For V2V channels that don't rely on wide-sense stationarity and uncorrelated scattering (non-WSSUS), a new non-geometrical stochastic model (NGSM) is developed. This model effectively extends the existing NGSM to incorporate the line-of-sight (Loss) component; it is based on a regular NGSM and uses a more precise way to re-create the realistic properties of V2V channels. Doppler power spectrum density (PSD), power delay profile (PDP), and tap correlation coefficient matrix are only a few of the statistical properties of the proposed model that are simulated and compared with those of the current NGSM in a variety of situations. We have shown that our theoretical deductions are true, and the simulation results back up this claim.
