Abstract

The single-carrier block transmission (SCBT) method has been considered for bandwidth efficiency in underwater acoustic (UWA) communication recently. The cyclic prefix (CP) in the SCBT method should be longer than the multipath spread, but a long CP reduces the data rate of SCBT UWA communications in significant multipath channels. The proposed scheme in this paper includes two parts: i) modified passive time reversal processing is used to shorten the large delay multipath channel, thus reducing the CP length; and ii) a hybrid time-frequency domain equalizer (HTFDE) is used to obtain spatial diversity and to remove the residual inter-symbol interference (ISI). The results of a lake experiment are presented to verify the efficiency of the proposed method.
