High-speed Vehicle-to-Vehicle Radio Channel Characteristics for Suburban and Municipal Lake Region at 5.9 GHz

摘要

A V2V radio channel measurement campaign with a maximum distance of 6 km was performed in high way of suburban and municipal lake Region, China. In this paper, a detailed description of the channel measurement campaign including antenna setups, channel sounder configurations and other related info is given. The received signal level (RSL) is shown and compared with the Plain Earth Loss model (PEL) and the Free Space Loss (FSL) model. It can be found that the PEL model predicts the fading dips at short TX-RX distances (within 150 m) well. The Power-delay profiles (PDPs) are demonstrated, from which the mean excess delay and the RMS delay spread are extracted. It can be found that the 90% of the mean excess delay and the RMS delay spread are within 27 ns and 102.1 ns, respectively. The Akaike Information Criterion (AIC) is used to estimate the best-fit amplitude distribution of the small-scale fading. The Rayleigh model is found to be the best-fit model with more than 90% incident percentage in the whole route.
