This paper focuses on the effects of large passing vehicles on vehicle-to-vehicle (V2V) radio channel characteristics under a typical urban intersection scenario. A V2V measurement is carried out at 5.9 GHz in Wuhan, China. Channel characteristics, including power delay profile (PDP), channel gain, root mean square (RMS) delay spread are analyzed in detail. According to the PDP, it is observed that the large passing vehicles and surrounding buildings will lead to strong reflection phenomenon, at the same time, the passing large vehicles can also cause non-line-of-sight (NLOS). The results present that the impact on the V2V radio channel from surroundings cannot be ignored. All these results in this paper can be useful to design the V2V wireless communication system.
