In this paper, bidirectional pair-wise communication between 2K nodes is considered. Each node has N antennas and wants to transmit d data streams to its communication partner. A single non-regenerative half-duplex relay with R antennas supports the communication. In this scenario, the process of interference alignment can be decomposed into partial signal(More)
—A wireless Ad Hoc network consisting of a source and multiple receiving nodes is considered. The source wants to transmit a common message throughout the whole network. The message has to be spread in a multi-hop fashion, as the transmit powers at the source and the nodes are limited. The goal of this paper is to find the multi-hop broadcast tree with a(More)
