| 声学频率梳信号（简称声梳信号）具有时延测量精度高、参数设计灵活性好的特点，在水下高精度距离测量、定位方面得到研究，也为通导一体化波形设计提供了新的方向。本文针对通导一体化背景下声梳信号在水声通信方面的应用，设计了声梳信号水声通信编码、调制、解调、解码技术方案。通过对信号进行相关性、时延估计特性和通信性能评估，并在此基础上开展了浅海水声信道海试实验，验证了声梳信号在实际海洋环境下的通信性能，并分析了影响其性能的主要因素。本文结果为推进声梳信号在通导一体化波形设计方面的应用提供了借鉴和参考。 |
| 英文摘要: |
| The acoustic frequency comb signal (abbreviated as acoustic comb signal) has the characteristic of high time delay measurement accuracy, good flexibility in parameter design, which has been studied in the field of underwater high-precision distance measurement and positioning, and thus provides a new direction for integrated waveform design. Aiming at the application of acoustic comb signal in underwater acoustic communication under the background of integration of conduction and communication, this paper designs the coding, modulation, demodulation and decoding technical scheme of acoustic comb signal in underwater acoustic communication. Through the evaluation of signal correlation, delay estimation characteristics and communication performance, and on this basis, the sea test experiment of shallow water acoustic channel is carried out to verify the communication performance of acoustic comb signal in the actual ocean environment, and the main factors affecting its performance are analyzed. The results of this paper provide reference for promoting the application of acoustic comb signal in the design of integrated conduction waveform. |
