摘要
提出并搭建了基于白光发光二极管的可见光通信模型,提出了一种用于改善现有可见光通信中频闪现象的编码算法与实现方案。理论分析了可见光器件频闪现象的产生原因、编码前后能量的分布情况和误码率等。实验验证并比较了该编码算法对频闪现象的改善情况。
This paper proposes and establishes a visible light communication model based on white light-emi-tting diode, proposes an encoding algorithm and an implementation scheme to suppress the flickering effect inprevious visible-light communication system. It analyzes the cause of the flickering effect of visible-lightdevices, the energy distribution before and after encoding and the bit error rate. The paper verifies and compares the improvement on the flickering effect with the help of the encoding algorithm by doing experiment.
