VDES COMMUNICATION SYSTEM OF COAST STATION BASED VDES

摘要

The present invention relates to a coast station communication system based on a VHF data exchange system (VDES). More particularly, the present invention relates to a coast station communication system based on a VDES for transmitting and receiving ASM and VDE messages in a marine VHF frequency band having an optimized design for a spectrum mask standard of a VDE recommended in ITU-R 2092.
