Abstract: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.
Keywords:high speed underwater acoustic communication  OFDM  FM
