A predefined channel coefficients library for Vehicle-to-Vehicle communications

Abstract

-It is noticeable that most of VANETs communications tests are assessed through simulation. In a majority of simulation results, the physical layer is often affected by an apparent lack of realism. Therefore, vehicular channel model has become a critical issue in the field of intelligent transport systems (ITS). To overcome the lack of realism problem, a more robust channel model is needed to reflect the reality.

Simulation and Analysis of Extended Spatial Channel Model in Vehicle-to-Vehicle Communication Environments

“…Under LoS conditions, the CIR of SCM V2V model can be represented by (9), where ϕ LoS is the phase of the LoS component, which follows the uniform distribution within (0, 2π] and σ s is the coefficient of lognormal shadow fading [37]. e symbol K denotes the ratio between the power of LoS paths and the power of clusters (Rician factor).…”
