Ergodic Layered Erasure One-Sided Interference Channels

Free registration required

Executive Summary

The capacity region of InterFerence Channels (IFCs), comprised of two or more interfering links (transmitter-receiver pairs), remains an open problem. The sum capacity of a non-fading two-user IFC is known only when the interference is either stronger or much weaker at the unintended than at the intended receiver. Recently, the sum capacity and optimal power policies for two-user ergodic fading IFCs are studied under the assumption that the instantaneous fading Cannel Sate Information (CSI) is known at all nodes. A sum capacity analysis for K-user ergodic fading channels using ergodic interference alignment is developed.
