| Research Abstract |
In order to prevent automobile accidents, reliable car-to-cat wireless communication, precise positioning and driver alarm system were investigated. Reliable communication is achieved by MIMO+ Adaptive demodulation, road side repeater, and new routing protocol based on the situation of the car(speed, relative position to the surrounding cars, and so on). Robust, low distortion and efficient RF devices were developed. Accurate pedestrian positioning system was realized by 2. 4 GHz wireless system. The error was less 1 meter which will be enough for avoiding the collision. Quick cognitive wearable interface was developed for car drivers.
