Incremental Relaying for the Gaussian Interference Channel with a Degraded Broadcasting Relay [PDF]
, 2011 This paper studies incremental relay strategies for a two-user Gaussian relay-interference channel with an in-band-reception and out-of-band-transmission relay, where the link between the relay and the two receivers is modelled as a degraded broadcast ...

On Secure Transmission over Parallel Relay Eavesdropper Channel [PDF]
, 2010 We study a four terminal parallel relay-eavesdropper channel which consists of multiple independent relay-eavesdropper channels as subchannels. For the discrete memoryless case, we establish inner and outer bounds on the rate-equivocation region.

Wireless Network Simplification: the Gaussian N-Relay Diamond Network [PDF]
, 2011 We consider the Gaussian N-relay diamond network, where a source wants to communicate to a destination node through a layer of N-relay nodes. We investigate the following question: what fraction of the capacity can we maintain by using only k out of the ...
