摘　　要：对车-车信道相关的特征参数做出了详细分析,运用射线跟踪方法对特定场景下的车-车通信信道进行了建模。建模中着重介绍了信道的多普勒扩展和相干时间,建模的结果为车-车通信系统的设计与优化提供了重要的参考。The characteristic parameters of Vehicle-to-Vehicle communication channel are described and the Vehicle-to-Vehicle channel in specific situations is modeled with ray-tracing method. In the model, we introduce the channel Doppler expansion and coherence time. The work can provide important references for the design and optimization of Vehicle-to-Vehicle communication systems.
