Semi-blind channel estimation relying on optimum pilots designed for multi-cell large-scale MIMO systems
Channel estimation in the presence of pilot contamination induced inter-cell interference (ICI) is a major challenge in large-scale multiple-input multiple-output (LS-MIMO) systems. In this paper, a subspace-based semi-blind channel estimator (SBCE) relying on an optimum pilot design (in the sense o...
