Abstract:The popularity of visible light communication (VLC) has increased recently because of the advancement of LEDs and the quantity of lighting bandwidth, which enables faster and more reliable transmission. High-speed transmission via LED networks is made possible by QAM-OFDM technology, which maximizes spectral efficiency and interference robustness to improve the VLC. For the proposed work, two OFDM modulation techniques (a PSK-OFDM and a QAM-OFDM with white LED, RZ/NRZ encoding schemes, and EDFA/SOA amplifiers)… Show more
