Multistage Relaying Using Interference Networks
Wireless networks with multiple nodes that relay information from a source to a destination are expected to be deployed in many applications. In this work, we consider multihopping decode and forward (MDF) relaying protocols for multistage half-duplex relay networks with no direct link between the source and destination nodes. Each state of the half-duplex network is considered as an interference network. Receivers in each state employ interference processing/cancellation; however, no cooperation across relay nodes is assumed for encoding or decoding. The scheduling of interference network states is optimized to maximize the rate for a given realization of channel gains. For arbitrary networks with two node-disjoint paths between source and destination, we analytically characterize strong and weak interference channel-gain regimes, and show an explicit two-state schedule that approaches the cheap relay cutset bound in these regimes. Numerical evaluation in example networks illustrate ...
