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...

Adaptive beam tracking for interference alignment in time-varying MIMO interference channels: Conjugate gradient approach
Based on a linear formulation to interference alignment, an adaptive algorithm for interference-aligning beam tracking in time-varying MIMO interference channels is proposed. It i...
