本文研究了道路波动对60 GHz频段IVC在LOS情况下传播特性的影响，采用2波模型计算接收功率，其中考虑了道路波动引起的道路反射波幅度和相移的变化。通过固定位置车辆间的传播试验验证了该模型的有效性。最后，利用该模型估计了通信车辆在起伏道路上行驶时的接收功率，并通过实测进行了验证。
This paper presents the effect of undulations in the road on the propagation characteristics in the LOS case for IVC in the 60 GHz band The received power is calculated by the 2-wave model, in which variations in the amplitude and phase shift of the road-reflected wave caused by road undulation are taken into consideration. The effectiveness of the proposed model was confirmed by a propagation test between vehicles with fixed positions. Finally, the received power when the communicating vehicles move on an undulating road is estimated using the model and this is validated by measurement.
