선택 중계는 다중 중계 노드가 있는 협력 시스템을 실제로 구현하기 위한 유망한 기술입니다. 그러나 최선의 릴레이를 선택하기 위해서는 선택 개체에서 글로벌 채널 지식이 필요하며, 이로 인해 상당한 시그널링 오버헤드가 발생할 수 있습니다. 본 논문에서는 부분적인 채널 상태 정보(CSI)를 갖는 듀얼 홉 증폭 및 전달(AF) 통신 시스템의 릴레이 선택 문제를 고려합니다. 양자화된 CSI를 사용하여 정전 확률이나 BER(비트 오류율)을 최소화하는 것을 목표로 하는 릴레이 선택 전략이 제시됩니다. 또한 정전 최소화 릴레이 선택을 위한 SNR 범위를 효율적으로 분할하기 위한 목표 속도 기반 양자화기와 BER 최소화 릴레이 선택을 위한 목표 BER 기반 양자화기를 제안합니다. 시뮬레이션 결과는 선택 엔터티에 대한 몇 비트 피드백으로 거의 최적의 성능을 달성할 수 있음을 보여줍니다.

Abstract: Selection relaying is a promising technique for practical implementation of cooperative systems with multiple relay nodes. However, to select the best relay, global channel knowledge is required at the selecting entity, which may result in considerable signaling overhead. In this paper, we consider the relay selection problem in dual-hop amplify-and-forward (AF) communication systems with partial channel state information (CSI). Relay selection strategies aiming at minimizing either the outage probability or the bit error rate (BER) with quantized CSI available are presented. We also propose a target rate based quantizer to efficiently partition the SNR range for outage minimized relay selection, and a target BER based quantizer for BER minimized relay selection. Simulation results show that near optimal performance is achievable with a few bits feedback to the selecting entity.

AB - Selection relaying is a promising technique for practical implementation of cooperative systems with multiple relay nodes. However, to select the best relay, global channel knowledge is required at the selecting entity, which may result in considerable signaling overhead. In this paper, we consider the relay selection problem in dual-hop amplify-and-forward (AF) communication systems with partial channel state information (CSI). Relay selection strategies aiming at minimizing either the outage probability or the bit error rate (BER) with quantized CSI available are presented. We also propose a target rate based quantizer to efficiently partition the SNR range for outage minimized relay selection, and a target BER based quantizer for BER minimized relay selection. Simulation results show that near optimal performance is achievable with a few bits feedback to the selecting entity.
