This paper investigates the performance of massive multiple-input multiple-output (MIMO) cellular systems with pilot contamination. We derive a closed-form approximation of the area spectral efficiency (ASE) for uplink multicell multiuser massive MIMO systems by using a uniformly distributed user location model. Considering a practical power consumption model, we obtain the area energy efficiency...
In this paper, the uplink sum-rate of the multi-cell multi-user massive MIMO system is studied under correlated Rayleigh fading channels. First, by considering pilot contamination effect, the equivalent system model of the massive MIMO is given with MMSE channel estimation. Then, the lower bound of the sum-rate is derived, and its asymptotical performance is studied when the base station antenna number...
