Abstract
In order to realize the video image transmission and the excellent lighting
function of the visible light communication system, a LED-
based visible light
communication method and system is proposed. Based on the field pr
o-
grammable gate array (FPGA) hardware,
the RS channel coding is applied to
the visible light communication system. A pulse position decision algorithm is
proposed,
which is applied to the receiver of the visible light communication
system to meet the error-free decision of the signa
l. The design of the system
is based on the analog-to-digital conversion circuit,
which provides a large
signal dynamic range for the pulse position decision algorithm,
and designs
the LED driver based on the bias circuit to realize the fast broadband modul
a-
tion of the signal. The test results show that the combined application of pulse
position decision algorithm and Reed-Solomon
codec can reduce the error of
system signal and meet the real-
time and reliable transmission of signal. The
system can display the received video in real time from the receiver,
and the
whole system communication distance up to 5 m.

communication based on LED technology is becoming a key research direction
of wireless optical communication [1]. The previous studies focus on the simula-
tion of modulation and coding, as well as the conceptual experimental demon-
stration, the purposes are to achieve fast and strong anti-interference ability of
VLC system [2] [3]. Based on the previous research, this treatise proposes a
