Signal-to-noise ratio modeling for vehicle-to-infrastructure communications

Abstract

In this contribution we propose an extension to the range-dependent modified Gilbert model introduced in [1]. With the proposed extension, the model can be used to generate realistic vehicle-to-infrastructure signal-to-noise ratio (SNR) traces along with the corresponding error patterns. We model the SNR as a combination of correlated large scale fading and small scale fading. The model parameters are derived from real-world measurements at 5.9 GHz. The accuracy of our simple and yet effective modeling approach is confirmed by comparing the model generated SNR traces to the measured performance.
