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.
