摘要
本项目设计一个基于FPGA的白光LED通信实验平台此可见光通信系统,对光通信系统采用直接调制-幅度调制方式。在可见光通信系统中,经过光发射机调制的光信号,在自由空间中传播后到达光接收机,采用"电处理,光传输"方式对信息进行处理,光电探测器是光接收机的关键,决定着光接收机的灵敏度。采用RS纠错码的信道编码技术对数据进行解调和纠错,提高数据的正确率和精确率。
In this project, a white LED communication experimental platform based on FPGA is designed, which adopts direct modulation and amplitude modulation for optical communication system. In the visible optical communication system, the optical signal modulated by the optical transmitter propagates in the free space and reaches the optical receiver. The "electric processing, optical transmission" mode is used to process the information. The photodetector is the key of the optical receiver, which determines the sensitivity of the optical receiver. The channel coding technology of RS error correction code is used to Demodulate and correct the data, and the accuracy and accuracy of the data are improved.
