Adaptive equalization technology in the marine noise feedback system

目前,水声通信系统面临的主要问题之一是由多途效应引起的码间干扰。为了确保水声通信的稳定性和可靠性,降低多图效率的影响,可以在接收端使用信道均衡技术。本文基于此技术设计的自适应均衡器可以根据信道传输的特性,动态地调整参数以克服多途效应的影响,实现水声通信系统的稳定性和可靠性。

At present,one of the main problems in underwater acoustic communication system is the inter symbol interference,which is caused by the multipath effect. In order to ensure the stability and reliability of the underwater acoustic communication and reduce the multigraph efficiency, channel equalization technique can be used in the receiver. The adaptive equalizer based on this technique can adjust the parameters dynamically according to the characteristics of the channel transmission,so as to overcome the influence of multipath effect,and realize the stability and reliability of the underwater acoustic communication system. In this paper,the application of adaptive equalization technology in underwater acoustic communication system is studied in detail.
