Exploiting Channel Correlations - Simple Interference Alignment Schemes with No CSIT
We explore a few selected multiuser communication problems where the possibility of interference alignment, and consequently the total number of degrees of freedom (DoF) with chann...

On the Effect of Interference on the Average Degrees of Freedom in MIMO Fading Ad-Hoc Networks
— We consider MIMO fading ad-hoc networks with Rayleigh co-channel interference (CCI) where, L transmitter/receiver pairs communicate independent information over the network, si...

Degrees of Freedom and Sum Rate Maximization for Two Mutually Interfering Broadcast Channels
— In this paper, we derive a precise expression of spatial degrees of freedom (DOF) for two mutually interfering broadcast channels (IFBC) as a function of arbitrary numbers of t...

A Two-Stage Precoding Method Based on Interference Alignment for Interference Channel Systems
— It was shown by Cadambe and Jafar that the interference alignment (IA) algorithm achieves the theoretical bound on degrees of freedom (DOF) for interference channel systems. Ho...
