Visible light communication using LED as receiver with the effect of ambient light

摘要

An indoor wireless communication using LED as both transmitter and receiver is presented in this paper. Ambient light noise from natural and artificial sources, would easily saturate the LED acting as sensor and decrease the indoor VLC system performance. Hence the receiver structure is designed using RC high pass filter to mitigate the ambient light noise. The measurement results shows that it could effectively reduce noise and improve the VLC system's stability and reliability.
