Abstract:
A visible light wireless communication receiver includes: a source code recognizing unit that receives a source bit stream and recognizes the source bit stream as source codes of a unit of a first number of bits; and a line coding unit that encodes each of the source codes into an encoding code of a unit of a second number of bits, the second number being larger than the first number. In particular, in the encoding code, the number of bits corresponding to 1 is the same as the number of bits corresponding to 0. Therefore, the change in brightness of lighting may be minimized in the visible light wireless communication.
