| Abstract(in English) | Visible light communication has been attracted attention because of its ubiquitous and safety. However, the faults of LED communication are that the optical power shows nonlinear characteristic to input current and the Peak to Average Power Ratio (PAPR) characteristic deteriorates. To reduce the PAPR, we propose a PAPR reduction method by applying an adaptive clipping with adding a peak mitigate signal. We also propose a performance enhancement by applying Frequency Symbol Spreading (FSS) and Priority Power selection (PPS) to improve the BER performance. With the proposed method, we achieve a significant PAPR reduction as large as 8dB compared with the conventional VLC-OFDM to maintain the superior BER. |
