Wireless optical transmission of 450 nm, 3.2 Gbit/s 16-QAM-OFDM signals over 6.6 m underwater channel

Not Accessible

Your library or personal account may give you access


We experimentally realized a gigabit underwater wireless optical communication system using commercially available 450 nm blue laser diode. 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.
