Abstract:

Precoding techniques can effectively eliminate interference among users in cooperative relaying systems,in which several users use the same time-frequency resources. In this paper,the applications of the multi-user precoding technology in relay systems are summarized,including the downlink and uplink precoding technologies. They are analyzed in different network topologies.

Key words: cooperative relaying, precoding, multi-user
