| Abstrak/Abstract |
Visible light communication (VLC) is a communication
technology using visible light as a transmission medium that can
have larger bandwidth than other wireless communications. VLC
has a standard of IEEE 802.15.7 which has two layess. One of the
layers is Physical Layer (PHY) II which has characterictic for
indoor and line of sight communication. In this layer, the standard
for data rate and optical clock rate is higher than the other types
of layers using on off keying (OOK) modulation. This research
investigated variation effect of clock rate, data rate, and Reed
Solomon (RS) coding to bit error rate (BER) of the received signal.
Nowadays, mostly data are pictures and videos. So, this research
also test the VLC PHY II to transmit a picture under the varied
conditions using peak signal to noise ratio (PSNR). All
investigations are built in simulation. The results show that the
lower RS coding rates, the lower BER values, and the higher
optical clock rate, the higher data rate obtained. Good quality of
picture is obtained with BER 10-4 and PSNR 39 dB. |
