【摘要】 本文研究了一种基于时延编码的远程水声通信技术 ,该技术利用线性调频 (LFM)信号矩形脉冲的时延值进行时延编码 ,在接收端采用时延估计技术进行时延解码。初步的海试结果表明 ,该技术可以实现 80km距离、4 .6bit/s数据率的信息可靠传输。更多还原

【Abstract】 A kind of long-range acoustic communication technique is studied in this paper. This technique uses different time delay values of the LFM pulse to code the transmitted information, and uses time delay estimation technique to perform decoding. The sea test results indicate that transmission of 4.6 bit/s over 80km distance can be achieved.更多还原
