Understanding and Managing Interference in
Wireless Networks
ABSTRACT: The understanding of point-to-point wireless communications channels with fading and
receiver thermal noise is mature. Recent advances, particularly in the area of multi-antenna
communications, have led to significant increases in the capacity and reliability of point-to-point links.
However, modern wireless networks are limited by interference from other links. While the information
theory for interference networks is still in its infancy, several techniques are being explored in the
research community for managing interference, while maintaining high spectral spatial reuse efficiencies
in these networks. These techniques include spatial user separation, interference cancellation, user
cooperation and relaying, dynamic spectrum access, and interference alignment. The first half of this talk
will be an overview of these techniques. In the second half of this talk, we will discuss some of our recent
results towards an understanding of the information-theoretic capacity of interference networks. We first
discuss a partial solution to the capacity of the two-user interference channel in the weak interference
regime, a problem that has been open for more than thirty years. We also discuss new techniques for
exploiting partial transmitter cooperation in interference channels in optimal ways.
