Abstract :
With the rapid development of OFDM (Orthogonal Frequency Division Multiplexing) technology and its own advantages, this technology has been studied actively in underwater acoustic communication recently to improve the data transfer rate and reliability. For the reason of Doppler shift effect in underwater acoustic channel, eliminating Doppler effect became the key of whether the OFDM system can be successfully used in underwater acoustic communication. In this paper, a twice Doppler shift compensation algorithm was proposed, which has high compensation precision, low computational complexity and implementing easily.
