Abstract

We analyze the performance of IEEE 802.15.7 colour shift keying (CSK) modulation for indoor visible-light optical wireless communication system. In CSK, the combined intensity of the R, G, and B of a white LED is held constant while their relative intensities vary. Design of multilevel CSK constellation for high bit rate transmission is a challenging problem. In this work, Voroni segmentation is employed for coding and decoding CSK constellation and system performance is analyzed. Monte Carlo simulation shows superiority of this method over other available CSK constellation design in terms of better received SNR for a given symbol error rate.
