Experimental Study on Flicker Mitigation in VLC using Pseudo Manchester Coding

Visible Light Communication is one of the promising technologies for wireless communication due to the possibility to useexisting LED lightening infrastructure to transmit data. LED has the ability to turn on and off very fast enough that ourhuman eyes can’t recognize so it can be used to transmit data via visible light along with illumination. But it faces flickerproblem due to the brightness discrepancies between ‘1’ and ‘0’ bit patterns inside a data frame. Various run length limited(RLL) coding scheme like Manchester code, 4B6B, 8B10B or VPPM can be used to solve flickering problem. So we proposepseudo Manchester codding which can transmit data without modifying LED modulator and demodulator circuit as well assolve flickering problem.
