“Information Theory of Wireless Networks: A Deterministic Approach”
Dr. David Tse


Description: 
Gaussian channels are commonly used models for multiuser  wireless communication. Unfortunately, the capacity of multiuser Gaussian  channels is unknown even for simple networks such as the single-relay  channel and the two-user interference channel. To make further progress in  understanding how to optimally communicate over these and more general networks, we propose a deterministic channel model which focuses on the interaction between the users rather than the noise in the system. We show: 

1) the analytical simplicity of this model by computing the capacities of several interference and relay networks based on this deterministic model; 

2) how the insights from the deterministic model can be translated into  finding near-optimal strategies for the Gaussian counterpart.
