| Summary: | Visible Light Communication or VLC is one of the breakthroughs in the world of
communication to address the frequency limitations that are used in radio
frequency based communication. As for several modulations, one of the most
common ones is On-Off Keying (OOK). The PAM (Pulse Amplitude Modulation) is
a modulation which is also an advanced version of OOK. The research on this has
been done a lot but limited to simulations, of course the simulation needs to be
proven by conducting experiments.
The purpose of this research is to design, simulate, implement PLC-4 based VLC
on FPGA and analyze performance in terms of BER and Data rate. In addition to
PAM-4 in this study additional modules were added in the form of Pulse shaping
and Matched filter as a solution to reduce Inter Symbol Interference.
The results of this study are that PAM-4 has worked with Pulse shaping and
Matched filter. The input that is sent is the same as that received, both through
modelsim simulation and SoC verification. A data transmission simulation of
10,000 byte has also been carried out and there are no errors. Based on the
simulation results, the resulting bitrate is 8 bits / 12 clock or 0.6 bit / clock. The
FPGA clock is mounted 5 ns to 0.6 bits / 5 ns or 1.2 Megabits / second. PAM-4 is
written in Verilog and verified with SoC using testbench in the form of C language. |
