摘要：
An adaptive resource assignment scheme for the multi-user cooperative communication systems with amplify-and-forward (AF) relays is investigated. We consider maximizing system capacity while guaranteeing the QoS (Quality of Service) of each user. A resource assignment is proposed using space-time coding with only source-to-relay channel gain information (CGI). It performs well in allocating relay nodes to the multiple source-destination pairs. The proposed algorithm enhances the system performance without loss of diversity.
