Ergodic Interference Alignment with Delayed Feedback

Information Theory 2013-03-14 v1 math.IT

Abstract

We propose new ergodic interference alignment techniques for KK-user interference channels with delayed feedback. Two delayed feedback scenarios are considered -- delayed channel information at transmitter (CIT) and delayed output feedback. It is proved that the proposed techniques achieve total 2K/(K+2)2K/(K+2) DoF which is higher than that by the retrospective interference alignment for the delayed feedback scenarios.
