This paper investigates the propagation characteristics of the inter-vehicle communication system operating at millimeter band. First, this paper proposes a new propagation model which takes into account the vehicle traffic and theoretically derives the path loss and delay profile characteristics using the ray tracing method. Next, this paper investigates the high speed digital transmission performance of the inter-vehicle communication system. Namely this paper theoretically analyzes the bit error rate, required transmission power and maximum available bit rate of the system. The results show that the vehicle traffic and the antenna size affect the transmission performance. Furthermore, this paper shows the improvement of propagation characteristics by diversity techniques. In addition, we propose a new inter-vehicle communication system with through repeater in order to achieve an adaptive network among vehicles without dynamic routing
