摘要

为了研究干扰车辆和穿越道路行人对车对车可见光通信系统的影响，本文提出了带有外界干扰的车对车2×2 MIMO可见光通信模型.该模型以基于市场加权灯束模型的汽车前照灯作为2个发射器，以光电探测器作为2个接收器，考虑了间隔车道车辆和过道行人对系统性能的影响.研究结果表明：当误码率小于为10

-4

时，同道、邻道和间隔车道车辆的纵向通信距离分别为：28 m、5~18 m、0 m；间隔车道的两车不能直接通信，但其前照灯发射光线会进入信号接收车辆从而对正常通信两车产生影响；行人穿越道路会使正常通信两车的误码率产生较大波动且存在积极影响，正常通信两车横向距离越大积极影响占比越高；本文提出的模型考虑了行人和车辆的干扰，为改善可见光通信在复杂交通网的应用效果提供了理论依据.

Abstract

In order to study the effects of interfering vehicles and crossing pedestrians on vehicle-to-vehicle visible light communication system

a vehicle-to-vehicle 2×2 MIMO visible light communication model with external interference is proposed in the paper. In this model

the automotive headlights based on the market-weighted model are considered as two transmitters and the photodetectors as two receivers. The effects of vehicles in the spaced lanes and pedestrians are considered. The results show that when the bit error rate is less than 10

-4

the longitudinal communication distances of vehicles in the same lane

adjacent lane and spacing lane are 28 m

5~18 m and 0 m

respectively. The two vehicles i

n the separate lane cannot communicate directly

but the light emitted by the headlights will enter the signal receiving vehicle and affect the normal communication between the two vehicles. Pedestrian crossing the road will make the bit error rate of normal communication vehicles fluctuate greatly and have a positive effect. The larger the lateral distance between normal communication vehicles

the higher the positive effect proportion. The model proposed in this paper takes into account the interference of pedestrians and vehicles

and provides theoretical basis for the application of visible light communication in complex traffic networks.
