Digital 4K video transmission over realtime water-air OWC-OFDM system with low-complexity transmitter-side DSP

摘要

A real-time 2.2-Gb/s water-air OWC system is successfully demonstrated with low-complexity transmitter-side DSPs, namely, geometric shaping and a joint PAPR reduction. With the DSPs, the system achieves a significant 8-dB ROP improvement at a BER of 3.8×10⁻³, and it enables four 4K-video transmissions.
