摘　　要：为满足高速水声通信的需要,在对正交频分复用(OFDM)技术的原理进行研究的基础之上,结合水声信道的特性,给出了进行二次频率调制(FM)的OFDM/FM实现方法,并通过仿真得到了该方法的性能。仿真结果表明,在多途扩展的信道条件下,基于OFDM/FM的水声通信系统仍可获得满意的性能。In order to meet the requirement of high speed underwater acoustic communication,the OFDM/FM method is given in the paper,which is based on the orthogonal frequency division multiplexing(OFDM)technique.The performance of this method is obtained through computer simulation.The simulation results indicate that,when multi-path spreading exists in the channel,the system based on OFDM/FM method still shows satisfactory performance.
