Optical MIMO-TDS-OFDM with Generalized LED Index Modulation
Authors: ,
Abstract: Recently, generalized light emitting diode (LED) index modulation scheme orthogonal frequency division multiplexing (GLIM-OFDM) was suggested to Li-Fi technology. In this paper, we proposed time domain synchronous OFDM (TDS-OFDM) as a modulation technique for generalized LED. In this scheme, TDS operates over the visible light communication channel to mitigate the inter-symbol interference by separating the complex TDS-OFDM signals into real and imaginary parts, then, exploiting the spatial multiplexing principle to transmit these signals through the channel. The suggested scheme performances based on computer simulation are explained in terms of BER performance and energy efficiency.
