abstract:
We discuss noisy network coding bounds on the capacity region of Gaussian multiple access relay networks. These networks feature a single destination node and multiple nodes that can be either sources or relays or both. We show that simple inner and outer bounds on the capacity region obtained from noisy network coding exhibit a submodular structure and differ only in a constant, which is independent of the channel parameters and grows linearly only in the number of dedicated relay n...    »
