<p>In this invention, methods on how light of a color can be generated by mixing light signals from multiple light sources, how a constellation is formed in a light color space for a modulation scheme, how the point of a received light signal in a light color space is determined by manipulating received signals from multiple photo detecting devices, how the point of a received light signal in a light color space is matched with a point of constellation to determine a recovered symbol at receiver, and how each pixel or a part of LCD displays and signboards can deliver data information to the receiver, are described. These methods can be applied to devise more efficient visible light signal processing and modulation schemes. By using the above methods, a modulation scheme is invented to realize more flexible and efficient visible light communications.</p> |
