- Title
- * Wireless Visible Light Communication using OFDM Sub-Carriers
- Highlight
-
A wireless visible light communication system using OFDM will be proposed and demonstrated.
The high peak-to-average power ratio (PAPR) in OFDM is considered a serious disadvantage in the
visible light transmitter due to non-linearities of LEDs. So, a parallel transmission system using two
LEDs has been employed to reduce the PAPR of OFDM signal. To prove the validity of our proposal,
the visible light transmitter and receiver fabricated using FPGA devices will be demonstrated. Here,
the number of OFDM sub-carriers with 16QAM modulation is 64.
