Abstract

Color Shift Keying (CSK) is a modulation method for visible light communications, which transmit information through three-band light of multi-color light source, outlined IEEE 802.15.7. In this paper, new CSK system using multiple full-color LEDs is proposed for realizing non-variable LED current control. Moreover, error vector magnitude (EVM) performance of the proposed system is demonstrated and evaluated. Consequently, when the distance between the plane of the LEDs and PD is larger than 12cm, the EVM performance of the proposed CSK is almost identical with that of the conventional CSK.
