Experimental Demonstration of a Dual-Mode Index Modulation 3D-OFDM VLC System

We propose and experimentally demonstrate a dualmode index-modulated three-dimensional orthogonal frequency division multiplexing (DMIM-3D-OFDM) visible light communication (VLC) system. DMIM-3D-OFDM improves the spectral efficiency of conventional 3D-OFDM by 25% by implicitly transmitting the index bits. Experimental results show that the transmission distance of DMIM-3D-OFDM is 1.44 times that of 3D-OFDM at the same data transmission rate. In addition, DMIM-3D-OFDM improves the maximum data transmission rate by 13.1% compared to conventional 3D-OFDM.

Abstract

We propose and experimentally demonstrate a dualmode index-modulated three-dimensional orthogonal frequency division multiplexing (DMIM-3D-OFDM) visible light communication (VLC) system. DMIM-3D-OFDM improves the spectral efficiency of conventional 3D-OFDM by 25% by implicitly transmitting the index bits. Experimental results show that the transmission distance of DMIM-3D-OFDM is 1.44 times that of 3D-OFDM at the same data transmission rate. In addition, DMIM-3D-OFDM improves the maximum data transmission rate by 13.1% compared to conventional 3D-OFDM.
