Cooperative Interference Alignment for the Multiple Access Channel

Abstract

We propose a novel communication technique for the multiple access channel (MAC), cooperative interference alignment (C-IA), which combines the ideas of interference alignment and successive interference cancellation. We prove that C-IA is sum-degree-of-freedom (DoF) optimal and derive bounds on the per-user DoF gain, showing that under mild conditions, nonzero DoF are achievable for all users simultaneously. An interesting open problem is extending the DoF analysis for delayed CSI.
