Research on 5G Network Coverage Optimization Data Transmission System with UAV Relay Enhancement

In the context of evolving 5G network technology, the fusion of unmanned aerial vehicles (UAVs) as relay nodes presents an innovative approach to enhance coverage and optimize data transmission. In this paper, orthogonal frequency division multiplexing (OFDM) technology, combined with advanced time-frequency synchronization algorithm and unique training sequence linear method, is used to improve the efficiency and reliability of data transmission in enhanced 5G networks. The proposed system architecture, combined with a special signal processing algorithm, shows a significant increase in data throughput and a decrease in packet loss rate through rigorous system simulation. It is worth noting that the simulation results show that the data transmission efficiency is increased by 30% and the packet loss rate is reduced by 20% under different environmental conditions, which shows the robustness and adaptability of the system. These findings highlight the transformative potential of drones in optimizing 5G network coverage, opening the way for future innovations in mobile communications technology.
