A MISO-OFDM Visible Light Communication System using LED Based on Subcarrier Multiplexing
A novel configuration of 2×1 and 3×1 multiple-inputs single-output (MISO) multiple-inputs sigle output visble light communication (OFDM-VLC) system is reported experimentally. The error vector magnitude (EVM) values varying with the input voltage of 2×1 and 3×1 systems is measured, and the best ranges of bias voltage is found, respectively. By setting the input voltage in the respective best range, the EVM values of 2×1 system, the EVM values and bit error rate (BER) of 3×1 system varying with transmission distance are presented. Without equalization, the transmission distance of the two systems can both be as long as 140 cm.
