Cover Story：Shi Meng, Zhang Mengjie, Chi Nan. Two input one output visible light communication system based on pulse amplitude modulation[J]. Opto-Electronic Engineering, 2019, 46(5): 180306.
The visible light communication (VLC) technology uses the on and off of the LED lights to transmit information while achieving illumination.Based on LED lights, VLC enables a combination of LED lighting and communication. The research team of Prof. Chi Nan, Department of Communication Science and Engineering, School of Information Science and Engineering, Fudan University, studied the MISO visible light communication system based on pulse amplitude modulation (PAM), and experimentally proves the advantages of this system in specific scenes. In addition, there are non-linear effects for key devices such as LED light sources and power amplifiers in visible light communication systems. Based on 2×1 MISO visible light communication system, this paper reports a novel equal probability coding mapping scheme for high-order PAM signals with two low-order PAM signals superposition in the optical domain.
