Title : Positioning the relay to achieve full diversity and minimize error probability in cooperative decode-and-forward relay systems 
Authors : Kyungchul Kwak, Sungeun Lee, Myeonghee Park and Daesik Hong 
Conference : European Wireless Communication Conference 
Abstract : Error propagation of source-relay (S-R) link limits the performance of decode-and-forward (DF) relay system and prohibits cooperative DF relay system from achieving full diversity gain. In order to resolve these problems, we first derive the criterion to achieve full diversity. It explains why the SNR of S-R link would be better than other links. Thus, we can obtain the exact distance range of relay to achieve full diversity and minimize the error probability of cooperative DF relay system by the proposed position strategy.
