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.
