A proposal of inter-vehicle communication based on spread spectrum radar

摘要

In ITS applications, it is important to establish the technique of inter-vehicle communication. This technique improves traffic flow and supports safe driving by transferring the information of driving operation and warning from collision avoidance radar, etc. We aim at the characteristics of spread spectrum technique having the realization of communication and ranging simultaneously, and superior to anti-interference. We develop the method of assignment PN codes for each vehicles based on vehicles' location after ranging by millimeter-wave radar using SS method.
