Abstract
A coding scheme for a color-shift-keying constellation in a visible-light communication system is provided, whereby a minimum number of flipped bits between symbols assigned to neighboring symbol points in the constellation is aimed. Improved assignments of symbol values to symbol points of the constellation may be provided, which may be capable of reducing a total Hamming distance between all symbol points in the constellation, thereby leading to a reduction of a bit-error ratio.
