摘要 OFDM(正交频分复用)是一种适合于在多径衰落和受限带宽信道中进行高速传输的技术。论文把OFDM技术应用于高速水声通信中,设计了一套基于OFDM的高速水声通信系统,阐述了OFDM水声通信系统中同步和信道估计的方法。海上试验证明了系统的有效性。 OFDM （orthogonal Frequency division multiplexing） is suitable for communication in multi--path fading and limited bandwidth channel. In this paper, a high speed underwater acoustic communication system based OFDM is proposed. A method is given for synchronization and channel estimation. The effectiveness of the system is experimentally tested at sea.
