Joint time-frequency interference alignment in the frequency-selective Gaussian interference channel
To make up for the limitation that the traditional interference alignment can only align the signal in one dimensional domain,a novel joint time-frequency interference alignment scheme was put forward in the frequency-selective Gaussian interference ...

Robust Lattice Alignment for K-user MIMO Interference Channels with Imperfect Channel Knowledge
In this paper, we consider a robust lattice alignment design for K-user quasi-static MIMO interference channels with imperfect channel knowledge. With random Gaussian inputs, the conventional interference alignment (IA) method has the feasibility problem

Interference alignment via controlled perturbations
In this work, we study the so-called leakage minimization problem, within the context of interference alignment (IA). For that purpose, we propose a novel approach based on controlled perturbations of the leakage function, and show how the latter can be used as a mechanism to control the algorithm's convergence (and thus tradeoff convergence speed for ...
