摘要：
In this paper, a direct current biased optical orthogonal time frequency space (DCO-OTFS) based full-duplex relay-assisted visible light communication system is proposed to enhance the spectral efficiency of visible light communications (VLC). The DCO-OTFS modulation method is described and the spectral efficiency of the system is analyzed. Simulation results indicate that the proposed method can achieve higher spectrum efficiency and robustness than the traditional direct current biased optical orthogonal frequency division modulation (DCO-OFDM).
