Inter-relay Interference management schemes for multi-user cooperative wireless networks

Abstract

In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for multi-user wireless networks. The first scheme (Interference management at relay station (IMR)) uses the decode-and-forward (DF) relaying protocol and treats the IRI at relay station. The second scheme (Interference management at mobile station (IMM)) uses the amplify-and-forward (AF) relaying protocol and treats the IRI at mobile station. Numerical results are given to confirm the advantage of the proposed schemes in enhancing interference management for wireless cooperative networks.
