Research on Signal Processing Model of 5G Technology in Ship Communication Network Optimization

This study aims to improve the transmission efficiency and stability of ship communication network by constructing a signal processing model based on 5G technology. The model mainly adopts adaptive beamforming algorithm to effectively suppress complex electromagnetic interference in the marine environment and improve the signal transmission quality. The adaptive beamforming algorithm can dynamically adjust the beam direction according to different signal propagation paths and interference conditions, thereby significantly improving the signal reception effect in the marine communication environment with significant multipath effect. In addition, detailed algorithm design and model simulation were carried out in the study. The simulation results show that the ship communication network using 5G technology has significantly improved signal quality and bandwidth utilization compared with traditional communication systems, especially in long-distance communication and severe weather conditions. The reliability of the system has been effectively verified. Data analysis shows that the signal bit error rate is reduced by about $\mathbf{2 5 \%}$ and the system transmission rate is increased by $\mathbf{3 0 \%}$.
