What is Channel Estimation in Massive MIMO Systems about?

This article presents a new channel estimator for multi-cell massive MIMO systems that addresses pilot contamination issues, improving upon existing least square (LS) and minimum mean square error (MMSE) estimators. The proposed estimator does not require knowledge of inter-cell large-scale fading coefficients and provides performance close to the ideal MMSE estimator. Analytical mean square error expressions are derived, showing that the proposed method achieves better estimation as the number of antennas
