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，研究了可靠的汽车无线通信，精确的定位和驱动程序警报系统。 MIMO+自适应解调，路边中继器和基于汽车情况的新路由协议（速度，与周围汽车的相对位置等）实现了可靠的通信。开发了稳健，低失真和有效的RF设备。准确的行人定位系统通过2。4GHz无线系统实现。错误较少1米，足以避免碰撞。为汽车驾驶员开发了快速的认知可穿戴界面。
