In massive multiple-input multiple-output (MIMO) systems, Pilot Contamination (PC) is
considered as a key barrier in enhancing the Spectral Efficiency (SE) for fifth generation (5G) …

The users at cell edge of a massive multiple-input-multiple-output (MIMO) system suffer from
severe pilot contamination (PC), which leads to poor quality of service (QoS). To enhance …

In this paper, we analyze the performance of the fractional pilot reuse (FPR) scheme with
pilot contamination mitigation in massive multiple-input multiple-output (MIMO) system. In …
