| 摘 要： | 水下航行器的运作与水声信道特性有着密不可分的关系,所以水声信道的研究对提高水下航行器性能起着非常重要的作用。从理论上介绍了水下航行器通信系统,着重分析了同一水声信道采用不同的调制解调方式(2ASK,2FSK,2PSK)时水下航行器系统误码率和信噪比的关系,然后通过MATLAB建立了系统仿真模型,得到了信噪比对误码率影响的仿真结果,并与理论结果进行了比较,对研究和设计水下航行器通信系统有着实际的指导意义。

| Abstract: | Because of the relation between the operation of the underwater aircraft and the characteristics of the underwater acoustic channel,the underwater acoustic channel is studied.Firstly,the underwater aircraft communication system is introduced in theory,and the relationship between system bit error of uniform underwater acoustic channel and different modulation and demodulation mode(2ASK,2FSK,2PSK)is analyzed.Then the simulating model is set up,and the simulating results show that there are introducting meanings in the study and design on the underwater aircraft communication systems. |

| Keywords: | underwater aircraft underwater acoustic channel SNR modulation and demodulation recursive least-squares algorithm bit error |
