Analysis of land digital communication systems with emphasis on possible applications in the maritime VHF band

Analiza kopnenih digitalnih komunikacijskih sustava s oxvrtom na mogucu primjenu u pomorskom VHF podrucju

Due to the increase in the number of users and the intensive usage of maritime very high frequency (VHF) band, there has been a need to increase the system capacity. Moreover, there is a need for new types of services, such as data transmission, which cannot be supported efficiently by the existing analog systems. Therefore, in this paper the characteristics of relevant land digital communication systems have been analyzed with the aim of identifying possibilities of maritime applications. The key parameters, under which the analysis was conducted, were selected on the basis of the assumption on the importance of coexistence of analog and digital modes of operation on adjacent channels and the possibility for gradual introduction of a new system. The analog mode of operation should be maintained to perform the distress, urgency and safety communications due to its robustness and distribution/prevalence. The systems that achieve high spectral efficiency and fit into the existing communication channels, which would facilitate their introduction, are proposed for possible application in the maritime VHF band.
