Abstract

In this work, we investigate the Interference Neutralization scheme on a 2×2×2 relay-interference channel w.r.t. the Cyclic Interference Alignment framework. We formulate sufficient and necessary conditions for this particular Interference Neutralization scheme to achieve the min-cut upper bound, i.e., two degrees of freedom, confirming the work on Aligned Interference Neutralization by Gou et al. Furthermore, we translate our proposed scheme to a generalized version of the asymptotic Aligned Interference Neutralization scheme based on spatial Interference Alignment.
