Abstract :
OFDM based acoustic communication system for underwater application is proposed. In order to mitigate a shrimp (impulsive) noise created by ocean living creature, time and frequency domain noise canceller is introduced. 2 dimensional DFT based channel estimation is also adopted to enhance the mobility of the communication system. Ocean measurement was performed in the experiment, and 53.0 m distance communication with Bit Error Rate of 0.01 was successfully confirmed. BER reduction by the proposed time and frequency domain shrimp noise canceller is also realized with 0.3 to 0.6 m/s mobility.
