Impact of cochannel interference on vehicle-to-vehicle communications at millimeter waves

In order to assess a vehicle-to-vehicle millimeter wave mobile radio network the evaluation of co-channel interference effects is of great importance. In fact the definition of a coverage strategy requires suitable frequency reuse thus producing the above-mentioned interference effects. As regards vehicle-to-vehicle communication, a scenario oriented to highways is considered; in this situation, a first step in estimating the transmission performance has to be done when the link between two communicating vehicles is affected by a single co-channel interferer. This analysis is carried out by considering anomalous propagation conditions both for the useful and the interference signals: to describe the system performance the authors not only consider their power levels, but evaluate the interfered system outage probability. Moreover, in order to counteract the effects of anomalous propagation some kind of diversity techniques are investigated. Finally, rain effects will be evaluated at different carrier frequencies
