本文给出了目前正在进行的关于水下通信信道特性实验研究的一些结果。采用一个专门设计的水下实验台来采集有关声信道和水声换能器传输特性的数据,此实验台同时对接收信号进行采样,并恢复复杂的基带信息。考察了信道对通信系统的影响,探讨了对水下自主航行体通信有影响的一些因素。 This paper presents some of the results of experimental studies currently underway on the characteristics of underwater communication channels. A specially designed underwater test bed is used to collect data on the transmission characteristics of acoustic and hydroacoustic transducers. The lab bench simultaneously samples the received signal and recovers complex baseband information. The influence of channel on the communication system was investigated, and some factors influencing the communication of underwater autonomous beacon were discussed.
