Abstract:
‘In maritime environments, cellular communication systems have difficult conditions such as long signal transmission distance and shadowing effects of the signal. Future cellular communication technologies aim to solve the difficult connection conditions in maritime environments. High altitude platform stations (HAPS), which take their place in non-terrestrial networks (NTN) studies, have a payload capacity that can host relay systems in maritime communication. In this study, decode and forward (DF) and intelligent reflecting surface (IRS) relay approaches placed on HAPS were subjected to performance comparison in the difficult maritime communication environment including shadowing and long-path losses. The effects of conventional terrestrial base stations and relay approaches without relays on the signal reception performance of the receiver were investigated. Simulations reveal the received power performances of IRS and DF relays and the effects of propagation losses on signal power levels. The obtained results provide important information for the design of cellular communication systems in maritime environments.’
