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.

Application of integrating VC cross-connecting function with OTN system

Dianxin kexue, 2018
Due to the advantage of rigidity pipeline,SDH is irreplaceable in carrying high priority service circuit.However,it will withdraw because of equipment ageing.A solution of OTN system with VC cross-connecting function was proposed for the situation which ...

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.

Is Declined Cognitive Function Predictive for Fatal Accidents Involving Aging Pilots?

Safety
Background. Civil aviation comprises airlines/charters and general aviation (GA). Currently, airlines are experiencing a pilot shortage, partly reflecting scheduled retirements mandatory for airline (but not GA) pilots aged 65 years, fueling a debate as ...

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.
