- W3157997782 abstract "Day by day, as people began to use daily communication, visible light communication is changing globally. Visible light communication (VLC) uses a visual modulation method named orthogonal frequency division multiplexing. This paper proposes a comparison of bit error rate (BER) of numerous 16 QAM and 64 QAM hybrid optical OFDM techniques including asymmetrically clipped absolute value optical OFDM (AAO-OFDM), spectral efficiency augmented hybrid asymmetrically clipped optical OFDM (SEA-HACO-OFDM), layered asymmetrically clipped optical OFDM (LACO-OFDM), asymmetrically clipped DC biased optical OFDM (ADO-OFDM) hybrid asymmetrically clipped optical OFDM (HACO-OFDM), asymmetrically clipped DC biased optical OFDM (EADO-OFDM), DC biased optical OFDM (DCO-OFDM), asymmetrically clipped optical OFDM (ACO-OFDM). The principle of each modulation method is demonstrated, and performance is compared in respect of bit error rate. BER is an essential parameter for the characterization of systems quality and efficacy. Signal strength will be better when the bit error rate is too small. Simulation results show that SEA-HACO-OFDM for both cases exhibits the best BER performance in comparison with other modulation techniques." @default.
