An underwater acoustic 64QAM OFDM communication system with robust Doppler compensation

This paper proposes an underwater acoustic OFDM communication system to transmit image or movie data from deep see AUV etc. to surface ship. In order to mitigate Doppler shift effect caused by transmitter and/or receiver movement, the OFDM receiver possesses additional time domain signal processing such as signal shrink-expansion processing and Doppler… CONTINUE READING
