摘　　要：为满足高速水声通信的需要,在对正交频分复用(OFDM)技术进行研究的基础上,结合水声信道的特点,提出一种基于OFDM技术的水声通信方法以此来克服信号的多径传输而引起的码间干扰,从而达到较高的传输速率和较低的误码率。In order to meet the requirement of high speed underwater acoustic communication,a underwater acoustic communication method that combined with the characteristic of underwater acoustic channel have been proposed,which is based on the orthogonal frequency division multiplexing(OFDM) technique and overcome ISI caused by signal multi-path transmission,in order to get higher transmission speed and lower ECR.

关 键 词：OFDM 高速水声通信 频率调制
