| 摘 要： | 设计了基于正交频分复用的高速水声通信系统,并进行了湖上和海上试验研究。湖试中,在6 000 m距离下,传输速率达到7.6 kbps,误码率低于10-4;海试中,在12 km距离下,传输速率达到8.3 kbps,误码率低于10-3。试验结果表明,正交频分复用技术可以较好地克服码间干扰,有效地利用水声信道带宽,达到高速水声通信的目的。

| Abstract: | A high-speed underwater acoustic communication system is designed.It was tested in a lake and in a sea respectively.In the lake,the bite rate reached 7.6 kbps within 6 km with the bit error rate(BER) lower than 10~(-4);in the sea,the bite rate reached 8.3 kbps within 12 km with the BER lower than 10~(-3).The experiments have shown that Orthogonal Frequency Division Multiplexing (OFDM) systems can effectively overcome the ISI(Inter-Symbol Interference) and improve the spectrum utilization to achieve high-speed underwater acoustic communication. |

| Keywords: | Orthogonal Frequency Division Multiplexing(OFDM) high-speed underwater acoustic communication |
