Impact of Metal Fences on V2V Channel in Suburban Intersection at 5.9 GHz

This paper focuses on the impact of metal fences on vehicle-to-vehicle (V2V) channel in suburban intersection. A signal-input signal-output (SISO) measurement campaign is conducted at 5.9 GHz in Wuhan, China. The V2V channel characteristics include power delay profile (PDP), small scale fading characteristics, channel gain and delay spread were analyzed. Akaike information criteria (AIC) is used to select the best fit distribution of amplitude fading, and results show Rician distribution offers better fit in line-of-sight (LOS) case in suburban scenario. In addition, the blocking of the metal fences caused a drop of about 7dB in channel gain and a rise of 62ns in root-mean-square (RMS) delay. The impact of metal fences on V2V channels cannot be ignored.
