Joint Pilot Design and Uplink Power Allocation in Multi-Cell Massive MIMO Systems

, 2018
This paper considers pilot design to mitigate pilot contamination and provide good service for everyone in multi-cell Massive multiple input multiple output (MIMO) systems. Instead of modeling the pilot design as a combinatorial assignment problem, as in

A Dirac sea pilot-wave model for quantum field theory [PDF]

, 2007
We present a pilot-wave model for quantum field theory in which the Dirac sea is taken seriously. The model ascribes particle trajectories to all the fermions, including the fermions filling the Dirac sea.

Pilot Assignment in Cell-Free Massive MIMO Based on the Hungarian Algorithm [PDF]

IEEE Wireless Communications Letters, 2020
This letter focuses on the problem of pilot assignment in cell-free massive MIMO systems. Exploiting the well-known Hungarian algorithms, two procedures are proposed, one maximizing the system throughput, and the other one maximizing the fairness across ...
