Abstract

This paper proposes two novel prediction-based adaptive selection cooperation schemes combined with a new relay selection strategy. In the proposed schemes, the destination predicts whether the transmission will be successful or not before a single relay is selected to transmit source's decoded data. Depending on the prediction, the destination feeds back a command to the whole network. Numerical results show that the proposed schemes combined with the relay selection strategy successfully reduce its outage probability, improve its throughput, save transmitted power, and prolong the lifetime of the network.

협력다이버시티는 무선채널페이딩에 강건하고 다중안테나기술에 비해 낮은 단말기 구현 복잡도를 제공하는 장점으로 인해 최근 각광받고 있는 기술이다. 본 논문에서는 새로운 중계단말기 선택 기법과 결합된 예측 기반 의사결정을 이용하는 적응적 협력 선택기법을 제안한다. 제안된 기법에서 수신단말기는 중계단말기와 수신단말기간의 순간 채널 상태 정보를 이용하여 선택된 중계단말기로부터의 전송이 성공할지 실패할지 여부를 예측한다. 수신단말기는 예측 정보를 이용하여 결정된 협력 선택 명령을 전체 네트워크에 전달한다. 실험결과를 통해 새로운 중계단말기 선택 기법과 결합된 적응적 협력 선택기법이 기존 기법들에 비해 불능확률(outage probability)을 줄이고, 시스템 성능(throughput)을 개선하며, 전송 전력을 절약하여 네트워크의 수명(lifetime)을 연장시키는 것을 보인다.
