Abstract

As the wireless communication technologies are being studied for application to maritime communication networks in a fusion of marine industries and IT technology, interference coordination techniques have been studied in the maritime heterogeneous networks. In this paper, we develop a simulator for measuring, verifying and evaluating performance of a maritime heterogeneous network. Unlike other previous simulators, the developed simulator applies enhanced inter-cell interference coordination (eICIC) that are being introduced in the 3GPP Release 10 for mitigating the cross-tier interference between ships. Furthermore, we investigate the effects of almost blank subframes (ABS) and cell range expansion (CRE) on the throughput of small cells in maritime heterogeneous networks by using the developed simulator.

해양 산업과 IT 기술의 융합으로 해상 통신에 대한 여러 무선통신 기술들이 논의됨에 따라 채널 선택에 따른 간섭 제어, 시간영역에서 간섭 제어 등 다양한 간섭 제어 방법이 시도되고 있다. 이를 위해 본 논문에서는 다양한 해양 통신 환경에서 시스템의 성능을 측정하고 검증 및 평가할 수 있도록 하향링크 시스템 레벨 시뮬레이터를 구현하였다. 제안하는 시뮬레이터는 기존의 이동통신 시뮬레이터와 달리 해상에서 선박 간 신호간섭을 조정할 수 있도록 3GPP Release 10의 주요 기술 enhanced inter-cell interference coordination(eICIC)을 적용하였다. 또한 개발한 시스템 레벨 시뮬레이터를 사용하여 eICIC의 주요 기술인 almost blank subframes(ABS)와 cell range expansion(CRE) 변화에 따른 소형 셀의 수율 분포를 도출하였다.
