A study on multipath propagation modeling in millimeter wave IVC

Inter-vehicle communication (IVC) systems using millimeter wave are widely researched. To realize a millimeter wave IVC system, analysis of propagation of the wave is very important. A multipath propagation model of millimeter wave is proposed. In IVC, the reception power of each vehicle varies by the movement of vehicles. In the proposed model, a direct path and a road-reflected path and their phase variation are taken into consideration. The delay spread between two paths is estimated from the path length of the received paths and two paths are combined to generate a desirable signal. A suitable method of reception under multipath fading is examined.
