Abstract
We propose new ergodic interference alignment techniques for -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 DoF which is higher than that by the retrospective interference alignment for the delayed feedback scenarios.
