Asymmetric Interference Alignment and Cancelation for 3-User MIMO Interference Channels

The notion of Degree of Freedom (DoF) of a communication network, also known as the capacity pre-log/multiplexing gain/effective-bandwidth, etc., is a fundamental concept in communication and information theory. With recent focus on capacity approximation, the DoF characterization becomes especially significant as it provides a capacity approximation whose accuracy approaches 100% in the high signal-to-noise ratio. Recently, the discovery of a new idea called Interference Alignment (IA) has shown that the DoF of wireless interference network can be much higher than what was believed.
