Abstract:
This paper presents a comparative study of stationarity time (Ts) of non-Wide-Sense Stationarity Uncorrelated Scattering (non-WSSUS) channel and path-loss characteristics between a Ray-tracing Veneris simulator and real-world data of Vehicle-to-Infrastructure (V2I) communication of Single-Input Single-Output (SISO) channel in a suburban environment at 5.89 GHz. The WSSUS assumption is often used to model wireless channels in order to simplify the analysis and design of communication systems. However, this assumption is not always valid for V2I channels, which can be highly dynamic and non-stationary. In this paper, a Ray-tracing simulator, namely Veneris, is used to generate synthetic V2I channel data. This data is then compared to real-world V2I channel data collected by a radio channel sounder, namely MaMIMOSA, in a suburban environment. The results show that the simulator accurately predicted the channel stationarity time of the real-world V2I channel, with a median of 560 ms compared to 550 ms for real data. Additionally, a Jensen–Shannon divergence value of 0.05 was found, suggesting a relative similarity between the simulated and real data distributions. The path-loss exponent factor was 3.5 for the simulator and 3.1 for real data.
