Visible light communication device, method and system
A visible light communication method performs visible light communication by using a visible light source. In searching a central frequency of the visible light source, a plurality of central-frequency training packets are sent, the central-frequency training packets including a plurality of central-frequency candidates, and one among the plurality of central-frequency candidates is selected as the central frequency of the visible light source based on a first decoding result on the plurality of central-frequency training packets. In searching a bandwidth of the visible light source, a plurality of bandwidth training packets are sent, the bandwidth training packets including a plurality of bandwidth candidates and the central frequency of the visible light source, and one among the plurality of bandwidth candidates is selected as the bandwidth of the visible light source based on a second decoding result on the plurality of bandwidth training packets.
