Abstract

In this paper, multiple-relay cooperative communication network with multiple antennas is considered. Applying the soft-decision-and-forward protocol to this system, pairwise error probability(PEP) is derived and then symbol error rate(SER) is also calculated. However, in general, signals are transmitted through the orthogonal channel in the multiple-relay cooperative communication network for the prevention of interference, which is inefficient in terms of the throughput. For the improvement of throughput, the relay selection is considered, where the relay having the maximum instantaneous end-to-end signal-to-noise ratio is chosen. Performance of the system is analyzed in terms of PEP and SER. As the number of the relay increases, relay selection method outperforms the conventional multiple-relay transmission system where all relays participate in the second time slot.

모든 노드에서 다중 안테나를 갖고 다중 릴레이가 존재하는 협동 통신망을 고려한다. 연판정 후 전송 기법을 적용하여 쌍 오류 확률을 구하고 이를 이용하여 심볼 오류 확률을 유도한다. 하지만 이러한 다중 릴레이 시스템 에서 간섭을 피하기 위해 일반적으로 전송률 측면에서 비효율적인 직교 채널의 사용이 요구된다. 이를 해결하기 위해 순시적인 신호 대 잡음의 비가 가장 큰 릴레이를 선택하도록 하는 선택 기법을 적용하고, 이 시스템에 대한 성능을 분석 한다. 또한, 릴레이의 개수가 증가할수록 모든 릴레이를 사용할 때보다 릴레이 선택 기법을 사용했을 때의 성능이 우수함을 보인다.
