Abstract An Incremental Coded Bi-directional Relaying (ICBR) scheme based on network coding and space-time cooperation is proposed, which utilizes the feedback information from nodes in the system. Cooperation in this way could improve resource efficiency and network throughput. The outage probabilities and the network-coding gain of different bi-directional relaying schemes are developed and analyzed. The numerical results show that compared with the other two schemes, ICBR scheme brings three-order diversity gain in fast fading channels and higher coding gain in slow fading channels. Furthermore, the theoretical results are verified with the simulation results.
