On the simulation of Weibull fading for V2X communications

Abstract

Propagation channel models play an essential role for proper computer performance evaluation of the Vehicle to Vehicle, and Vehicle to Infrastructure (V2X) communication systems. Several stochastic, tapped delay line channel models are proposed in the literature. These involve either Rice and Rayleigh distributed taps or Weibull distributed, correlated, and non-stationary taps. This paper focuses on the latter case. It discusses methods for simulating the Weibull fading complex envelope, and suggests the necessity to deal with a non-uniform phase distribution in order to assess the performance level of the V2X communication.
