外界干扰下车对车2×2 MIMO-VLC系统研究
Research of Vehicle-to-Vehicle 2×2 MIMO-VLC System Based on External Interference
摘要
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 2x2 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 con-sidered.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 in 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 commu-nication vehicles,the higher the positive effect proportion.The model proposed in this paper takes into account the interfer-ence of pedestrians and vehicles,and provides theoretical basis for the application of visible light communication in com-plex traffic networks.关键词
