摘　　要：介绍了一种独特新颖的车载LED光无线通信系统,该系统应用到室内场景,能彻底解决在车库和隧道中出现的GPS难以快速定位和AM/FM信号丢失等问题。建模仿真结果表明,在使用常用LED阵列等的条件下,该系统能提供一种高度可靠的单信道,其信噪比可以达到59.5dB,远高于信号稳定最低要求的15.6dB,数据传输速率达到14Mbit/s。A novel on-board optical wireless communication system using white LED light is presented. The system, when applied to indoor scenarios, can thoroughly resolve the problems of the difficulty in speedy positioning of GPS and the loss of AM/FM radio signal in garage and tunnel. The results of simulation on the model built show that with a common LED array the system can provide a highly reliable single-channel for data transmission with a data transmission rate of 14 Mbit/s and a signal to noise ratio reaching 59.5dB, much higher than 15.6dB, the minimum requirement for signal stability.
