Abstract
If visible light communication is to be used against large background noise in indoor environment, low frequency noise should be avoided. To maintain the advantages of LED lighting while transmitting signals, LEDs should be dimmable and free from flickering effect. In this paper, the spectrum of transmission signal is shifted toward high frequency for this purpose. Specifically, we propose a subpulse-VPPM scheme, which can be designed using only digital components, and we implement a test-bed for performance measurement.
