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.

为了防止汽车事故的发生，研究了可靠的车对猫无线通信、精确定位和驾驶员报警系统。通过MIMO+自适应解调、路边中继器和基于汽车状况（速度、与周围汽车的相对位置等）的新路由协议，实现可靠的通信。开发了坚固、低失真和高效的RF器件。通过2. 4 GHz无线系统。误差小于1米，足以避免碰撞。快速认知可穿戴接口是为汽车驾驶员开发的。
