초록

본 논문에서는 중계기의 위치에 따른 협력 통신의 성능을 분석한다. 이를 통해 최적의 중계기는 송신단과 수신단의 신호 전송의 성능을 높이거나 송신단의 신호를 수신단이 복호하지 못하였을 경우 재전송을 하는 일종의 송신단 역할을 한다. 본 논문에서는 최적의 중계기를 선택함으로써의 성능 향상을 보이며 관련 수식을 유도한다.

In this paper, we analyze effects of positions of relays on the performance of cooperative communication networks. From this, the best relays are chosen to assist transmitting the signal to the destination or to replace the source to retransmit the signal to the destination whenever the destination incorrectly receives the signal from the source. As the results, we show the significant improvement on performance of schemes choosing best relays, which is compared to the performance of other cooperative schemes. Moreover, the simulation results that match exactly with the theoretical results prove the correctness of the analysis.
