基于四基色LED的CSK和PAM联合调制系统
Combined CSK and PAM scheme for visible light communication based on quadLED
摘要
Abstract
A combined scheme of color shift keying (CSK) and pulse amplitude modulation (PAM) based on quadLED is proposed in this paper.Through attaching CSK signals to the non-zero PAM signals,the visible light communication system can transmit the information on two dimensions,one is the light intensity ratio and the other is the total light intensity.Simulation results show that with the same symbol error rate and information transmission rate,the hybrid system has about 4dB signal-to-noise ratio gain more than the traditional CSK schemes which are put forward by the IEEE 802.15.7 under the additive white Gaussian noiseenvironment.关键词
