摘要
在船舶信息化技术飞速发展的今天,绝大部分船载设备都需要与船载通信控制系统建立联系,从而能够实现对整个船舶运行状态的实时监控。但是在有限的船载空间中,需要安置众多的通信交换设备,多种设备之间必然存在通信干扰,因此为了提高通信网络的性能,需要对网络中的干扰进行滤除。本文结合船载通信设备的特点和网络拓扑结构,介绍了一种自适应干扰滤除算法,该算法能够主动侦测系统中的干扰信号,通过反馈网络,对干扰信号的特征进行主动学习,然后在网络中的节点对噪声进行滤除,从而大大提高了船舶通信系统的整体性能。
In the rapid development of ship information technology, most of the ship-borne equipment need to establish contact with the ship-borne communication control system, so as to realize the real-time monitoring of the whole ship running status. However, in the limited space of the ship, the need to place a large number of communications switching equipment, a variety of devices must exist between the communication interference, so in order to improve the performance of the communication network, the need for network interference. Based on the characteristics of the shipborne communication equipment and the network topology, an adaptive interference filtering algorithm is introduced. The algorithm can actively detect the interference signal in the system and actively learn the characteristics of the interference signal through the feedback network. The noise in the network is filtered out by the nodes in the network, which greatly improves the overall performance of the ship communication system.
