An important research area in underwater acoustic (UWA) communication is the development of bandwidth efficient modulation and demodulation techniques with low complexity. Over the past two decades, single carrier with time domain equalization (SC-TDE) and orthogonal frequency division multiplexing (OFDM) were used for high data rate underwater information transmission. The performance of high data...
Single carrier modulation with frequency domain equalizer is proposed for underwater acoustic channel. An unique training sequence, viewed as cyclic prefix, is inserted into transmitted sequences so that low complexity minimum mean square error (MMSE) frequency domain equalization (FDE) is used for combating the inter-symbol interference in the receivers. Maximum likelihood estimation for robust initial...
