Modeling the Channel Time Variation Inside Moving Vehicle

In this letter, we propose a new stochastic model for the time variation of wireless channel inside the moving vehicle. In the classical Jakes’ model, the receiver is assumed to move at a certain speed relative to the surrounding reflectors. However, when the receiver is inside a moving vehicle, the receiver is relatively static to the surrounding reflectors, while the reflectors (as well as the receiver) move at a certain speed relative to the ground. A novel stochastic model for this kind of channel time variation is proposed in this letter, which can be employed to model the channel time variation inside the moving vehicle in a more accurate manner.
