摘　　要：为实现节能环保,适应不同场合下对不同照明亮度的需求,将现有可见光通信(VLC)系统调光控制方法进行了总结分析,并提出了基于码重门限校验编码的调光方案,在实现通信功能的同时实现亮度控制。仿真结果表明,该方案能够进一步提高频谱利用率,并实现更优的误码性能。In order to achieve energy savings and adaptation to the requirements of different brightness levels for different occasions, this paper summarizes the existing dimming control methods for visible light communication systems, and proposes a new code-based scheme which can achieve dimming control as well as data transmission. Simulation results show that the proposed scheme can further improve spectral efficiency and obtain better error performance.
