(事前公開アブストラクト) Image sensor communication (ISC) enables multiple and simultaneous signal reception because of its ability spatially separate multiple sources. Therefore, ISC is an attractive solution for an outdoor mobile environment, in particular, in the field of intelligent transport systems (ITS). In ISC, since a transmitter position moves in an image plane according to vehicle movement, detection and tracking of transmitter is critical issue for robust data reception. Such movement referred to as optical ow causes ISC channel to fluctuate and must be considered to receive the signal accurately. In this paper, we conducted vehicle vibration measurement in well paved road and analyzed the frequency characteristic. According to the measured result, we proposed a vehicle vibration model and determined its parameters.
