Experimental demonstration of visible light communication based on sub-carrier multiplexing of multiple-input-single-output OFDM

摘要

In this paper, a novel configuration of VLC system based on sub-carrier multiplexing of MISO OFDM is proposed. The system consists of a 2×1 MISO array of white LEDs to transmit and receive data. The data is respectively modulated by two sub-carriers at 6.25MHz and 12.5MHz. An overview of the system configuration is described, and the transmission experiment is setup. The experimental results and the relationship between the system BER and transmission range are also investigated.
