Outline of Final Research Achievements

In our studies, Vehicle-to-Vehicle Communication and Ranging Systems using Spread Spectrum Technique with Visible Light called Visible Light Boomerang Systems were discussed. First, Visible Light Boomerang System which uses headlights and taillights with LEDs was studied. Next, we discussed Visible Light Manchester Boomerang System. This system uses Manchester codes. Furthermore, Laser Radar Visible Light Boomerang System was proposed. The proposed system combines existing automotive laser radar with Visible Light Boomerang System. At last, we proposed an upgraded Laser Radar Visible Light Bidirectional Communication Boomerang System for reliable ranging and bidirectional vehicle-to-vehicle communications. From computer simulations, it is confirmed that a vehicle can communicate with the target vehicle and can measure the distance between the two vehicles at the same time even if a little interference wave exists.
