CSK-Based DCO-OTFS for Visible Light Communications
This paper investigates a color shift keying (CSK)-based direct-current-biased optical orthogonal time frequency space (DCO-OTFS) waveform for visible light communica-tions (VLC) systems. In the proposed structure, red-green-blue (RGB) intensity components generated by 8CSK modulation are mapped onto a Hermitian-symmet...
