Relay positioning for multicast relay networks [PDF]
2013 IEEE International Symposium on Information Theory, 2013 The relay positioning problem is addressed for low signal-to-noise ratio Gaussian multicast relay networks where the objective is to maximize the multicast flow. A network coding based decode-and-forward (DF) strategy is presented that achieves strictly larger rates than a previously-studied routing based DF strategy.

Robust MMSE Precoding Strategy for Multiuser MIMO Relay Systems with Switched Relaying and Side Information [PDF]
, 2013 In this work, we propose a minimum mean squared error (MMSE) robust base station (BS) precoding strategy based on switched relaying (SR) processing and limited transmission of side information for interference suppression in the downlink of multiuser ...
