초록

본 레터는 두 통신 선박이 다수의 릴레이 선박의 협력으로 데이터를 교환하는 해상 통신 시스템을 고려한다. 이 때 릴레이 선박들이 채널 상태 정보에 따라 아날로그 네트워크 부호화와 디지털 네트워크 부호화를 적응적으로 선택하는 방법을 제안하고, 이러한 적응 전송 시 최적의 릴레이 선박을 선택하는 기준을 함께 제공한다. 모의실험 결과 제안한 방법이 단일 네트워크 부호화를 적용하는 기존의 방식보다 향상된 성능을 제공함을 볼 수 있다.

This letter considers a ship-to-ship communication system in which two ships exchange their information with the help of multiple relay ships. For the system, we propose a novel relay scheme that allows relay ships to select a method between analog network coding (ANC) and digital network coding (DNC) adaptively based on channel state information. We also provide a relay selection criterion in supporting the proposed adaptive network coding. The simulation results show that the proposed scheme outperforms the conventional scheme employing only the ANC or only the DNC.
