SNR-threshold based Adaptive Loading for PAM-Fast-OFDM over Optical Wireless Communications
2018
We propose and experimentally demonstrate the first adaptively-loaded PAM-Fast-OFDM over OWC using a simple yet effective SNR-threshold based loading algorithm. Results show >4-dB sensitivity improvement, and a 5.2-Gbit/s transmission with ∼44% capacity enhancement is achieved.
