We first compare their performances under dynamic range constraints of the LEDs and observe lower peak-to-average power ratio (PAPR) for SC-FDE schemes as compared to orthogonal division multiplexing (OFDM) techniques. We further introduce decision feedback equalizer (DFE) for SC-FDE schemes and demonstrate performance improvement in multi-tap indoor VLC channels. © 2015 IEEE.eninfo:eu-repo/semantics/closedAccessDecision Feedback EqualizerDecomposed Guadrature Optical SC-FDEDynamic Range ConstraintOn-Off Keying SC-FDEVisible Light CommunicationConference Object2015-August10.1109/ICTON.2015.7193307N/AN/A
