This paper proposes a reshaped orthogonal frequency division multiplexing (R-OFDM) scheme for intensity modulation/direct detection visible light communication (VLC) systems, where an LED consisting of red, green, blue, and amber chips (RGBA-LED) is adopted as the transmitter. In R-OFDM, the signal is adjusted by signal separation and biasing after clipping (BAC)/scaling before clipping (SBC) operations for transmitting in the RGBA-LED. We optimize both biasing and scaling factors for the BAC… CONTINUE READING
