A study on space division DS/SS Inter-Vehicle Communication system using circular array antenna
Ken Yamamoto, Kohei Ohno, Makoto Itami · 2009
In this paper, a space division DS/SS IVC (direct sequence/spread spectrum, inter-vehicle communication) scheme using a circular array antenna is studied. A circular array antenna can reduce the interference between PN codes due to the congestion of many vehicles. The circular array antenna which is used in this paper has a characteristic that the directivity of the antenna can be controlled easily when a direction of target vehicle is known. The scheme to control the directivity of a circular array antenna based on the information which is exchanged between each vehicle.
