摘要：
The Orthogonal Frequency Division Multiplexing (OFDM) technique is an effective method for suppressing multi-paths interference of underwater acoustic (UWA) channels. In this paper, a new communication system based on OFDM is presented, aiming at reliable 70km shallow water communications. The convolutional coding and frequency-domain equalization are also applied for the improvement of the OFDM system performance. The simulation results show that this proposed system can transmit data stream with low bit error rate (BER) in 70km UWA distance.
