Capacity Bounds on Multi-Pair Two-Way Communication With a Base-Station Aided by a Relay

Free registration required

Executive Summary

The simplest bi-directional relay network consists of a pair of terminal nodes that wish to exchange messages through the use of a single relay. While the capacity of this channel is still unknown in general, it has been of great recent interest (see references in and) due to its relevance in future wireless networks. The single relay, single pair bidirectional relay channel has been extended in a number of ways: the consideration of a single bi-directional link using multiple relays, and the consideration of multiple bi-directional links sharing a single, common relay.
