Recently, cooperative communication is shown to be a promising approach to achieve spatial diversity. The performance improvement by cooperative communication heavily depends on selecting suitable relay node. Therefore, designing effective relay assignment algorithm becomes critical in wireless cooperative networks. Although many studies focus on relay assignment problem, none of them concerns the interference problem, produced by relay nodes. In this paper, we investigate how the interference impacts the relay assignment problem. In addition, we give a relay assignment algorithm with interference mitigation for cooperative communication.
