What is Energy-Efficient U-OFDM for VLC about?
Researchers at the University of Edinburgh have developed a novel method for visible light communication (VLC) using unipolar OFDM (U-OFDM) that achieves up to 5 dB lower electrical energy usage and up to 2 dB lower optical energy usage compared to other state-of-the-art VLC modulation techniques. Previous methods of U-OFDM and ACO-OFDM sacrificed half the information capacity compared to DC-biased optical OFDM, but the new method avoids this capacity loss, making it significantly more energy efficient whil
