Detailed Description

Computes the channel condition for the V2V Urban scenario.

Computes the channel condition following the probabilistic model described in M. Boban, X.Gong, and W. Xu, “Modeling the evolution of line-of-sight blockage for V2V channels,” in IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016.
