Abstract :
The performance analysis of a multi-user multi-cell massive multiple-input multiple-output system that applies a conventional channel estimation technique, namely the linear minimum mean square error over correlated Rician fading is investigated. Based on the analysis, it is found that increasing the line-of-sight component can enhance the estimation accuracy.
