Research on doppler technology based on OFDM underwater acoustic communication

首先分析水声信道多普勒技术。为提高信道的复用性,本文基于拷贝相关的多普勒估计算法在不损失通信质量的前提下提高通信效率。仿真实验说明,本文所设计的算法与未复用帧结构的算法相比提高了通信效率。

In this paper analyzed the underwater acoustic channel Doppler technology. In order to improve the channel of reusability,It related to the use of copy-based Doppler estimation algorithm without losing the communication quality of the premise to improve the communication efficiency. Finally,simulation experiments show that the algorithm improves the communication efficiency,compared with nonmultiplexing frame structure algorithm.
