Degrees of Freedom Region of a Class of Multi-source Gaussian Relay Networks

Characterizing the capacity of Gaussian relay networks is one of the fundamental problems in network information theory. However, for Gaussian relay networks, the signal transmitted from a node will be heard by multiple nodes (broadcast) and a node will receive a superposition of the signals transmitted from multiple nodes (interference) and there exist fading and noise, which make the problem complicated. To overcome such difficulties, simplified wireless network models have been developed that provide intuition towards an approximate capacity characterization of single-source Gaussian relay networks.
