Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A colour coding and/or decoding unit, comprising: an optical transmitter configured to implement a coding scheme for a colour-shift-keying constellation in a visible-light communication system, wherein the colour-shift-keying constellation includes sixteen symbol points, S 0 -S 15 , wherein the symbol points have a numbered order and location within the colour-shift-keying constellation according to IEEE 802.15.7 specifications, and wherein each of the…
