Abstract
White light-emitting diodes (LEDs) are becoming widely used in both illumination and communication applications. In this paper, a visible light communication system is described, which employs blind equalization schemes at the receiver. The blind equalization schemes can both improve the data transmission bandwidth significantly and compensate the signal distortion dynamically. Off-line analysis shows the eye-diagram is observably improved at 10 Mb/s operations using 1 MHz bandwidth white-light LED.
