In inter-vehicle communication(IVC), many studies are focused on DS/SS CDMA(Direct Sequence / Spread Spectrum, Code Division Multiple Access) scheme. This scheme, however, has a problem of the increase of interference between PN codes due to increase of the number of vehicles. The use of space division transmission is an effective solution for this problem. In this paper, a circular array antenna is used to perform space division transmission, and the effectiveness of the proposed method is examined by computer simulation.
