Joint Pilot Sequence Design and Power Control for Max-Min Fairness in Uplink Massive MIMO [PDF]

arXiv, 2017
This paper optimizes the pilot assignment and pilot transmit powers to mitigate pilot contamination in Massive MIMO (multiple-input multiple-output) systems. While prior works have treated pilot assignment as a combinatorial problem, we achieve a more tractable problem formulation by directly optimizing the pilot sequences.

Pilot Reuse Factor with Large Scale Fading Precoding for Massive MIMO [PDF]

arXiv, 2017
The fundamental limitation of massive MIMO technology is pilot contamination effect. This effect occurs during uplink training when terminals use the same orthogonal signals. In this paper, a pilot reuse factor with large scale fading precoding is proposed to mitigate the pilot contamination effect.

Pilot Reuse Strategy Maximizing the Weighted-Sum-Rate in Massive MIMO Systems [PDF]

arXiv, 2017
Pilot reuse in multi-cell massive multi-input multi-output (MIMO) system is investigated where user groups with different priorities exist. Recent investigation on pilot reuse has revealed that when the ratio of the coherent time interval to the number of users is reasonably high, it is beneficial not to fully reuse pilots from interfering cells.

RRH based Massive MIMO with "on the Fly" Pilot Contamination Control [PDF]

arXiv, 2016
Dense large-scale antenna deployments are one of the most promising technologies for delivering very large throughputs per unit area in the downlink (DL) of cellular networks. We consider such a dense deployment involving a distributed system formed by multi-antenna remote radio head (RRH) units connected to the same fronthaul serving a geographical ...
