对可见光通信的调制模块进行研究，并且对各种调制方案的调光功能进行了研究和比较。-we propose a MPPM to offer both functions of modulating data-stream and controlling the brightness at the same time.From our studies, we show that MPPM is superior to variable on–off keying (VOOK) and var

IEEE802.15.7定义可见光通信的标准，主要是对调制方案和调光支持的研究。-IEEE 802.15.7 provides dimming adaptable mechanisms for flicker-free high-data-rate visible light communication.
