Vehicle-to-vehicle propagation channel for truck-to-truck and mixed passenger freight convoy

摘要

This paper presents first measurement results on truck-to-car and truck-to-truck propagation channels at 5.9 GHz. We measured the channel with a self-built real-time channel sounder with multiple antennas at both transmitter and receiver. We present sample results for two safety-related scenarios in a highway and urban environment, respectively. We analyze the measured data with a high-resolution parameter extraction algorithm, which provides both spatial and temporal characterization of the channel. The results show that the channel exhibits a higher Doppler dispersion in the highway scenario than in the urban scenario. Besides, the metallic trailer, which is higher than the antenna, acts as a strong reflector when the trucks face each other and an effective shadowing object when the trucks face away.
