| description | In this paper, in order to accommodate dimming demands for illumination, which is an essential requirement for visible light communication (VLC), a dimming control scheme with high power and spectrum efficiency is proposed. In the proposed method, a negative hybrid asymmetrically clipped optical orthogonal frequency division multiplexing (NHACO-OFDM) is first investigated and then combined with HACO-OFDM signal for multiplexed transmission. By adjusting the proportion of these two signals, the novel dimming control scheme can be achieved. Simulation results conducted that the proposed scheme can support optical wireless communication with higher power and spectrum efficiency and carry out the dimming control with broad dimming range for illumination, compared with conventional counterparts under various illumination conditions. |
