【摘要】 水声通信系统一直是船舶航行通信领域的研究重点,随着信息化技术的快速发展,船舶通信系统也变得越来越复杂,航道探测和声呐通信等技术的使用也越发频繁,但是随着数据量的快速增长,水声通信由于其复杂的技术瓶颈,目前正面临诸多困难。在水声通信中,信道自适应均衡技术的出现,在一定程度上解决了上述难题,本文着重分析水声信道的传输特点,对LMS自适应均衡算法的核心部分进行建模,并通过分析建模数据对该种算法的误码率进行分析研究,对此算法提出进一步的改进措施。更多还原

【Abstract】 Underwater acoustic communication system has been the focus of research in the field of ship navigation communications,with the rapid development of information technology,ship communication systems are becoming increasingly complex,the use of waterways sonar detection and communication technology has also become more frequent,but with rapid growth in data volume,underwater acoustic communication due to its complex technical bottleneck currently facing many difficulties. In underwater acoustic communication channel adaptive equalization technologies emerge,to a certain extent,solve the problems encountered above,this article focuses on the transmission characteristics of underwater acoustic channel,the core part of LMS adaptive equalization algorithms are built mold,and comparative study of algorithms BER data modeling through analysis of algorithm further improvements.更多还原
