Computes the channel condition for the V2V Urban scenario.
Computes the channel condition following the specifications for the V2V Urban scenario reported in Table 6.2-1 of 3GPP TR 37.885.
3GPP TR 37.885 defines 3 different channel states for vehicular environments: LOS, NLOS and NLOSv, the latter representing the case in which the LOS path is blocked by other vehicles in the scenario. The document defines a probabilistic model to determine if the channel state is LOS or NLOSv, while the NLOS state is determined in a deterministic way based on the buildings deployed in the scenario. For this reason, this class makes use of an instance of BuildingsChannelConditionModel to determine if the LOS is obstructed by buildings or not.
