A study on application of inter-vehicle communication and ranging system using spread spectrum technique

摘要

This paper reports a study on application of Inter-vehicle Communication and Ranging System using Spread Spectrum Technique with Regeneration of pN Signal in Target Vehicle for 2-way communication called PN Regeneration Type Improved Boomerang Transmission System to multi targets. The PN Regeneration Type Improved Boomerang Transmission System uses synchronous PN signal that is regenerated in a target vehicle. Using this system, each vehicle can communicate with the other vehicle and Vehicle-A can measure the distance between two vehicles at the same time with robustness against interference wave. In this paper, we propose PN Regeneration Type Multi Target Boomerang Transmission System. In the proposed system, PN Regeneration Type Improved Boomerang Transmission System is applied to multi targets. From computer simulations, it is confirmed that Vehicle-A can communicate with Vehicle-B and Vehicle-C and can measure the distances of AB and AC at the same time even if a little interference wave exists.
