Abstract: The interference channel consists of two independent transmitter-receiver pairs sharing the same medium. The receivers see combinations of the two transmitted signals - and wish to decode their desired message in the presence of the other pair's interfering message. This is a remarkably simple looking and practically relevant channel model - particularly well motivated by wireless communications - whose capacity region has remained unknown for over 40 years. In the first part of the talk, we outline the best known inner and outer bounds to the capacity region and highlight channels for which they almost, or exactly, coincide. In the second part of the talk we focus on recent results for the interference channel and some of its variations. The goal is to understand what is known about the interference channel, and to realize that interference can be dealt with in a number of ways. Biography: Natasha Devroye is an Associate Professor in the Department of Electrical and Computer Engineering at the University of Illinois at Chicago (UIC). She obtained her Honors B. Eng in Electrical Engineering from McGill, her MSc and PhD in Engineering Sciences from Harvard, and was a lecturer at Harvard for 1 year before joining UIC in 2009.
