摘要：
With the vigorous development of the navigation industry, the VDES(VHF Data Exchange System) has received extensive attention from various research institutions. In order to solve the multipath fading problem in VHF wireless channel transmission, this paper integrates FMT (Filtered Multitone Modulation) technology into VDES ground subsystem, redesigns the system time slot structure under the protocol framework, constructs the underlying communication link of VDES ground subsystem based on FMT. Simulation results show that the performance of the system using FMT technology is slightly better than that using OFDM technology, and the spectrum utilization and frequency offset resistance are improved. Research demonstrates that the introduction of FMT into VDES can effectively solve the multipath interference problem and has certain value for the practical application of VDES.
