Experimental Demonstration of Visible Light Communication using White LED, Blue Filter and SoC based Test-Bed

In this paper, data transmission using a white LED and blue filter is demonstrated. The conventional white LEDs are produced by combining blue LEDs with yellow phosphor coating. This combination generates white light. However, the yellow phosphor coating has bandwidth limiting effect. As a result, the data rate of the transmission is limited. One of the method that can be used to cope this effect is by employing blue filter at the receiver. This method filters out the yellow components. To test the method, an experimental SoC-based test-bed using a HW/SW co-design approach is developed.
