Abstract:
There is provided a method of transmitting a visible light signal in visible light communication, including binarizing data to be transmitted into a binary bit representation, encoding the data for transmission by modulating one or more of a plurality of light emitting regions between a first state and a second state based on the binary bit representation of the data, and transmitting the visible light signal in the form of light emitted by one or more of the plurality of modulated light emitting regions, the visible light signal being decodable to obtain the data. There is also provided a method of transmitting a visible light signal in visible light communication which includes modulating one or more second sets of light emitting regions within the capture region between a first state and a second state based on the bit representations of one or more previous data for enabling error detection. Corresponding methods of receiving a visible light signal and systems are also provided.
