Design of Network Codes for Multiple-User Multiple-Relay Wireless Networks

Wireless relay channels and networks have recently attracted substantial research efforts with the goal of improving performance in terms of energy efficiency, throughput or coverage. In relay networks, one or more intermediate nodes are employed to help the sources to transmit the information. Various transmission protocols with different complexity and performance have been proposed for these networks, e.g., amplify-and-forward and decode-and-forward. By allowing information processing at the intermediate nodes, network coding has been originally proposed for networks where the links consist of noiseless bit pipes. Here, network coding is able to achieve the min-cut for multicast transmission.
