Abstract

Research developments and applications in the underwater acoustic communication fields have been a challenge for researchers. In this paper we present a study about image transmission over underwater acoustic channels. We present the 256 OFDM transmission technique with BPSK modulation, forward error correction (FEC)-Hamming (7,4), least square (LS) and minimum mean square error (MMSE) equalizations. The simulation results show that FEC-Hamming gives a good performance, e.g. 5 dB SNR results in 0.0017 BER and 20.84 dB SNR. The performance of LS equalization and MMSE equalization at the receiver are compared. MMSE equalization need approximately 12 dB SNR for the BER of 0.001, or 2 dB lower than the LS case.
