摘　　要：为提升舰船设备通信质量及稳定性,设计舰船多信道无线网络抗干扰算法。建立舰船多信道模型,获取舰船多信道网络信号,提取舰船多信道网络干扰信号特征、计算干扰信号特征数据邻域距离、可达距离和异常因子,从信号中挖掘干扰信号;改进小波阈值算法对舰船多信道无线网络干扰信号进行抑制,实现舰船多信道无线网络的抗干扰。实验结果表明:该算法应用后,舰船的多信道无线网络的频率变化稳定,抗干扰效果较好,可保证接收端完整接收发射端的信号。To improve the communication quality and stability of ship equipment,a multi-channel wireless network anti-interference algorithm is designed for ships.Establish a ship multi-channel model,obtain ship multi-channel network signals,extract interference signal features from ship multi-channel network,calculate neighborhood distance,reachable distance,and anomaly factor of interference signal feature data,and mine interference signals from signals;Improve the wavelet threshold algorithm to suppress interference signals in ship multi-channel wireless networks and achieve anti-interference in ship multi-channel wireless networks.The experimental results show that after the application of this algorithm,the frequency variation of the multi-channel wireless network on ships is stable,and the anti-interference effect is good,which can ensure that the receiving end receives the signal from the transmitting end completely.
