摘　　要：水声信道具有极其严重的时变多途扩展、多普勒扩展以及有限的通信频带资源等特点,因此建立可靠而高速的水声通信链路面临巨大的挑战。常用的水声通信调制方式主要有单载波调制和多载波调制2种,与水声多载波调制方式相比,水声单载波调制不存在峰均比等问题并且有较高的频谱利用率。本文对水声单载波通信体制的国内外研究状况进行了概述,并针对水声单载波通信体制中的时域均衡技术以及自适应技术进行归纳,最后总结国内外主要研究方向并对水声单载波通信技术进行展望。Underwater acoustic(UWA)channel has extremely serious time-varying multipath spread and Doppler spread characteristics and limited communication frequency band resources.Therefore,establishing reliable and high-speed UWA communication links is an enormous challenge.At present,two kinds of modulation modes are commonly used in UWA communication:single-carrier modulation and multi-carrier modulation.Compared with the multi-carrier modulation,the single-carrier modulation has no peak-to-average ratio and has a higher spectral efficiency.This paper mainly summarizes the research status of UWA single-carrier communication system at home and abroad,makes a conclusion on the time domain equalization technology and adaptive technology in the UWA single-carrier communication system,and in the end,summarizes the main research directions at home and abroad and the prospect of UWA single-carrier communication technology.
