Abstract :
The enhanced visible light communications (VLC) system with transmission distance of 6m is demonstrated using transmission path design and forward error correction code in this paper. The experimental results suggest that based on the given power and 10-3 bit error rate, in comparison with uncoded system, average communication distance increases 45%, communication area increases 236% with LDPC code.
