Abstract
A method and device for visible light communication is disclosed. The method comprises selecting a first sequence and a second sequence of light intensity frequencies to represent a first symbol and a second symbol, respectively, for embedding data. The method comprises further transmitting a light signal. The light signal comprises time periods in which a light intensity of the light signal is sequentially controlled according to the selected sequence of light intensity frequencies. Thereby, a frequency hopping light signal is generated, in which data may be embedded. The light signal may be generated and transmitted by the device comprising a light emitter.
