Optimum beamforming in the broadcasting phase of bidirectional cooperative communication with multiple decode-and-forward relays

Abstract

This letter focuses on the broadcasting phase of bidirectional cooperative networks with multiple decode-and-forward relays. In this phase, the relays first combine the information-bearing symbols transmitted by the sources, and then broadcast them back to the sources in order to achieve bidirectional communications. Two different combining methods at the… (More)
