Abstract

Addressing the interference problems faced by aviation broadband communication systems in complex multipath channels, this paper investigates anti-multipath interference technology in OFDM-based systems. By analyzing the multipath characteristics of aviation channels, an enhanced OFDM system is designed, focusing on key technologies including time-domain interpolation channel estimation using comb-type pilots, adaptive MMSE equalization, and anti-multipath synchronization. Simulation results demonstrate that, under typical aviation multipath channels, the proposed technical solution significantly improves the system's bit error rate performance compared to traditional methods, demonstrating particularly good robustness under harsh channel conditions. This study provides an effective technical approach for the implementation of high-performance aviation broadband communication systems.
