As an emerging wireless communication technology, visible light communication (VLC) is one of the effective solutions for the shortage of wireless spectrum resource. In this work, a low-complexity design scheme of orthogonal frequency division multiplexing (OFDM) system is proposed based on the mask invariable characteristics of the received signal-to-noise rate of VLC in the electrical domain. The scheme is verified by the experiments. The experimental results show that, compared with the adaptive equal bits transmission scheme, the proposed adaptive OFDM system makes full use of the bandwidth resources of wireless optical channel, and it shows improvements in transmission rate and BER performance.
