Performance Analysis of Channel Effect on NC-OFDM Maritime Communication System in Indonesia Seas

摘要

As the largest archipelago in the world, Indonesia has an enormous potential from maritime area. The best support system for manifesting that is with establishing maritime wireless communication system in Indonesian seas and oceans. In this research, we collect the data from previous research to determine the type of most Indonesian seas and oceans. However, this research only focuses on Java Sea and Karimata Strait. From the investigation, those seas are classified in Douglas sea scale 4 and 5, which are in moderate and rough condition. Based on those data, we model the maritime channel for maritime communication system with determining the fading path parameters in the available non contiguous orthogonal frequency division multiplexing (NC-OFDM) system, then we perform the numerical simulations of the model. It can be concluded from results that the bit error rates (BER) for both models are around 10^-2 which still have a good potential to be developed further and implemented in Indonesian maritime communication system.
