By implementing 16-QAM-OFDM modulation, we achieved data rate of 3.2 Gbit/s with a BER of 6.83×10-4 over 6.6 m channel. © 2016 OSA.Light transmission; Underwater acoustics; Blue laser diodes; Data rates; Underwater channels; Underwater wireless optical communications; Optical communicationWireless optical transmission of 450 nm, 3.2 Gbit/s 16-QAM-OFDM signals over 6.6 m underwater channelconference paper10.1364/cleo_si.2016.sw1f.12-s2.0-85010661792
