초록

본 논문에서는 이동형 중계기 시스템에서 네트워크 진입절차를 거치지 않는 분산적 주파수 분할기법을 제시하였다. 이를 위해 각기 중계기들의 주파수 분할의 기준 신호, Frequency Indicator(FI) 신호와 이를 전송하기 위한 Energy Detection(ED) 구간을 정의 하였다. 또한 중계기간 통신을 원활하게 하기 위하여 중계기 자신에게 연결된 단말을 이용하여 인접한 곳에 위치한 중계기들에게 ED구간에 FI신호를 전송하는 기법을 정의하였다. 그리고 이를 바탕으로 여러 토폴로지 환경에서의 시뮬레이션을 진행하여 셀 수율에서 향상이 있음을 확인하였다.

In this paper, we proposed that decentralized frequency allocation scheme(DFAS) without network entry procedure between relays in mobile relay system. Frequency Indicator(FI) signal which is the reference signal of frequency division of each relay and Energy Detection(ED) region are defined. In addition, the mobile connected to the relay transmits the FI signal to neighbor relays in order to facilitate communication between relays. Finally, by using this scheme, the cell throughput improvement is confirmed.
