A new geometrical channel model for vehicle-to-vehicle communications

We have presented a new analytical model of the Doppler spectrum in the V2V environment based on scattering objects distributed along both sides of the roadway. Comparisons with examples of measured spectra from the suburban environment show improved agreement with the shape of the spectra compared to the double-ring model. We believe the new model could be beneficial for both wireless emulators and network applications. For example, the model would improve the accuracy of wireless emulators, in turn making more accurate hardware performance evaluations (such as BER) possible. Similarly, an accurate physical level channel model allows the evaluation of different MAC protocols under realistic conditions.
