Abstract

In this paper, ray tracing (RT) is used to analyze the characteristics of train‐to‐train (T2T) wireless channel in 2.1 GHz frequency band, including path loss, multipath clustering, delay spread, Rice factor, angular spread, and channel nonstationarity. It is found that the change of environment has a great influence on the characteristics of the wireless channel, which not only causes the birth and death of multipath clusters but also makes the channel appear nonstationary characteristics. In order to characterize the nonstationarity of the T2T wireless channel, we introduce the time correlation coefficient (TPCC) of the power delay profile (PDP), analyze the nonstationarity of the T2T wireless channel, and give the quasi‐stationarity distance. The results are basically consistent with the measured data.
