Inter-vehicle communication and ranging system using FH/SS technique

Abstract

In recent years, ITS (intelligent transport systems) are studied and developed for safe driving supports, etc. In many systems for ITS, inter-vehicle communication systems and ranging systems are very important. Therefore, the inter-vehicle communication and ranging system using spread spectrum technique called SS Boomerang Transmission System has been proposed. Using this system, a vehicle (vehicle-A) can know the information of a target vehicle (vehicle-B) and range distance between two vehicles at the same time. In the conventional reports for the SS Boomerang Transmission Systems, they used direct sequence spread spectrum (DS/SS) technique. In this paper, inter-vehicle communication and ranging system using frequency hopping spread spectrum (FH/SS) technique called FH/SS Boomerang Transmission System is proposed. From computer simulations, it is confirmed that the proposed system is better than the conventional DS/SS Boomerang Transmission System when interference waves exist.
