Abstract	ABSTRACT The conventional best relay selection based on all the channel information for the first and second hops in dual-hop systems has a large consumption of resources for channel feedback. In this paper, we analyze the average bit error rate for partial relay selection based on the channel information only for the first hop in dual-hop decode-and-forward relaying systems, where we assume independent Rayleigh fading channels. In particular, we provide an exact and closed-form expression for the average bit error rate of M -ary QAM. Also, through numerical investigation, the performance of the partial relay selection is compared with the performance of the best relay selection, and the performance is evaluated for different numbers of relays and various average channel power ratios for the first and second hops. 키워드 : 디코딩 후 전달 중계 시스템, 부분 중계 노드 선택 기법, 레일레이 페이딩 채널, 비트 오차율 Key word : Decode-and-forward relaying system, partial relay selection, Rayleigh fading channel, bit error rateJournal of the Korea Institute of Information andCommunication Engineering
