A Method for Generating Correlated Taps in Stochastic Vehicle-to-Vehicle Channel Models

Most of the existing channel models are based on the assumption of wide sense stationary uncorrelated scattering (WSSUS) properties, which are not suitable for time-varying vehicle-to-vehicle (V2V) channels. A method for generating correlated taps in stochastic V2V channel model is proposed in this paper, which represents the non-WSSUS properties adequately. With the method for generating correlated taps, the proposed tapped delay line channel model is correlated both in the amplitude part and the phase part. In the model, the amplitude statistics follows the Weibull distribution, and the phase statistics follows the linear function of uniform distribution, which are more accurate to represent the fading properties of V2V channel. Furthermore, simulation results show that the proposed model can generate correlated V2V channel with arbitrary amplitude and phase correlation coefficients accurately.
