Broadcast Capacity Region of Two-Phase
Bidirectional Relaying, Tobias J. Oechtering, Clemens Schnurr, Igor Bjelaković, Holger Boche · 2008
In a three-node network bidirectional communication be- tween two nodes can be enabled by a half-duplex relay node with a decode-and-forward protocol. In the first phase, the messages of two nodes are transmitted to the relay node. In the second phase a re-encoded composition is broadcasted by the relay node. In this work the capacity region of the broadcast phase in terms of the maximal probability of error is determined. It is characterized by the mutual informations of the separate channels coupled by the common input.
