Abstract

The DFT-SOFDM is a high speed underwater acoustic communication technology even for underwater military communication. In this paper, different kinds of modulation schemes were compared in the underwater acoustic DFT-SOFDM communication system. The comparison results in real underwater acoustic channels showed that, when the underwater acoustic channels were static, each scheme had the same BER performance; when the channels were changing quickly, the BER performances of different modulation scheme were different.
