A Model of OFDM based Maritime VHF Communication System for Data Exchange
Polish Maritime Research, 2018 In the maritime Very High Frequency (VHF) band, there are no systems for transmitting large amounts of data. Therefore, it is necessary to develop new systems that would modernize the Global Maritime Distress and Safety System (GMDSS), significantly ...
