Interference Channels with Generalized Feedback

SPEAKER: Professor Daniela Tuninetti, ECE Department, University of Illinois-ChicagoABSTRACT: In the past years, there has been a renewed interest to characterize the ultimate performance of InterFerence Channels (IFC). Classical IFCs model competition among uncoordinated source-destination pairs. IFCs with generalized feedback model scenarios where the sources can sense the current channel activity, like in wireless channels, and use this information to communicate cooperatively. Although cooperative communications is not equivalent to virtual MIMO communications, it has been shown that it benefits the performance of all the involved source-destination pairs without increasing neither the transmit powers nor the channel bandwidth. In this talk, we will review recent progresses for IFCs with and without generalized feedback. We will describe the currently best achievable and outer-bound regions. We will conclude by comparing those regions for Gaussian IFCs under different feedback configurations, and pointing out open problems.HOST: Prof. Giuseppe Caire, caire@usc.edu
