Abstract

Visible light communications (VLC) with light-emitting diodes (LEDs) has attracted applications, such as data communications, lighting control, and light interaction. In this paper, we propose a system by which two LED devices are used for two-way VLC while also providing illumination. We consider Manchester encoding with on-off keying for transmission. A reception scheme in which the LEDs themselves are used as receivers by sensing in the OFF periods is considered. A synchronization scheme to achieve frame-and symbol-level synchronization is also proposed. A prototype of the proposed system is designed and the communication performance is evaluated.
