Channel Covariance Matrix-Based Pilot Assignment for Massive MIMO Systems

In this letter, we propose a simple pilot assignment scheme for the massive MIMO systems with spatially-correlated channels. The proposed scheme, which is designed based on the average channel gains and the covariance matrices of the channels, effectively mitigates the pilot contamination and improv...
