Topics in Network Information Representation and Communication
In the second part of this dissertation, the problem of determining the capacity region of the Gaussian interference channel is discussed. New outer bounds on capacity are derived, and a very simple power-splitting scheme is shown to be within 1 bits/s/Hz of the capacity of the channel for all …
