Joint User Clustering and Graph Coloring Based Pilot Assignment for Cell-Free Massive MIMO Systems

Pilot contamination due to pilot reuse seriously mitigates the performance of the cell-free massive multiple-input multiple-output (MIMO) systems. In this paper, we propose a joint pilot assignment scheme that employs user clustering and graph coloring (UC-GC) to reduce pilot contamination. The prop...
