A new inter-vehicle communications (IVC) channel model

A new model of the transmission channel between moving vehicles is presented in this paper. The approach consists of three major parts: the modelling of the road traffic, the modelling of the environment adjacent to the road lane, and the actual modelling of the wave propagation between the vehicles. A ray-optical approach is used to model the wave propagation, which allows for wide-band as well as narrow-band analyses of the channel. A characteristic time series of impulse responses of the IVC-channel can therefore be calculated, which can be directly used for system simulations. Simulation results are compared to wide-band measurements at 5.2 GHz of the IVC-channel, yielding a good agreement.
