Massive MIMO Channel Estimation Considering Pilot Contamination and Spatially Correlated Channels
Keyword(s):
In this letter, we present a study on linear channel estimators and their respective mean square error (MSE) expressions acknowledging spatially correlated channels and pilot contamination. We also investigate the impact of imperfect channel covariance matrix knowledge.
