Abstract
This study presents a field programmable gate array (FPGA) implementation of an orthogonal frequency division multiplexing (OFDM) optical wireless communication transmitter. Two OFDM techniques, namely DC biased optical OFDM and asymmetrically clipped optical OFDM, are considered. For each, the dynamic range of the signal is used to optimise signal conversion from digital to analogue domain. A dual-mode transmitter with the same transmission bit rate for both techniques is implemented. The switch from one mode to the other can be performed according to light dimming without reprogramming the FPGA.
