キーワード：Advanced modulation and demodulation, Digital signal processing techniques for optical communications, Transmission and Propagation, Transmission Subsystems
We experimentally demonstrated a 10.74-kb/s 4-CSK transmission over an OCC system with the assistance of QPSK-like 2-D constellation in YCbCr/CIElab color space. Under only 420-lux illuminance, a BER of <3.8×10-3 was achieved in the experiment.
