高速水声通信中的相位补偿研究

Phase Compensation for Underwater High-speed Acoustic Communication

利用相位补偿来解决高速水声通信中的载波恢复问题 ,并分析了联合相位补偿和信道均衡时的系统性能。研究结果表明 :使用相位补偿后 ,均衡器可以有效地抵抗频率偏移造成的信道相位旋转 ,跟踪频率偏移能力提高了一个数量级以上。

This paper deals with the phase compensation as a way to recover carriers for underwater high-speed communication, and analyses the performance of the system when joint equalization and the phase compensation are implemented. The results show that the equalizer is able to effectively resist the channel phase rotating introduced by frequency offset with the phase compensation, and the tracking capability of equalizer is improved more than one magnitude.
