摘要：

By taking into account moving scatterers and velocity variations of terminals, a non-stationary vehicle-to-vehicle (V2V) channel model under non-line-of-sight (NLoS) scenarios is proposed. Under 2D non-isotropic scattering scenarios, the closed-form expression of the time-variant temporal correlation function (TCF) for the proposed model is derived and analyzed. The derived expression is a general solution and includes most of the existing results as special cases, i.e., stationary scenarios, constant velocities of terminals, or fixed scatterers. In addition, the derived TCF has a good agreement with the simulated and measured results.
