The adaptive OFDM system can obtain the channel state information according to the channel estimation, and adaptively adjust the transmission parameters of the transmitter, so as to improve the system performance. Among them, OFDM is a multi carrier modulation technology, which has the advantages of high spectrum utilization, anti multipath interference, anti burst noise, error and so on.
The introduction of adaptive OFDM technology in VLC, can improve the system capacity, improve the quality of transmission, the system has more flexibility, improve the performance of the system. In the field of wireless optical communication, the research of this technology has become an important direction. According to the literature published by existing researchers, most of them are based on basic and theoretical research, and few studies have been done on visible light communication technology and adaptive OFDM.
