An Adaptive Transceiver Design for Visible Light Communication

Abstract

Wireless Visible light communication has been attracting many researchers attention recently the reasons are that visible light communication have some advantages which do not exist in radio frequency communications. Many researches done in visible light communication fields the most of these researches focused on how to achieve higher communication data rates and much less focused on the designing steps of the visible light communication transceiver to be utilized for indoor applications within short ranges. In this thesis designing and implementing of a visible light communication transceiver is successfully accomplished. The designed system composed of two main sections the transmitter section and the receiver section. The system uses two ATmega328P chip microcontrollers. Light emitting diodes used at the transmitter section as the transmitting module. The light emitting diode illumination light wave acts as the carrier of the transmitted signals. At the receiver section a photo detector and an LCD display are used to realize the signal reception. The final tests of the system showed that the design realizes indoor visible light short distance data transmission and verifies a reliable transceiver for visible light communication.
