Non-Isotropic Fading Channel Model for the Highway Environment

This paper investigates the properties of several non- Jakes Doppler spectra proposed for the vehicle-to-vehicle non- isotropic scattering environment of the open highway. Expressions for the ideal model correlations, level-crossing rates, and average fade durations are derived. The classic Clarke channel model is modified to generate fading signals corresponding to the non-isotropic scattering profiles. The simulation results match well with the theoretical ideal channel.
