Graph‐colouring based pilot assignment to mitigate downlink pilot contamination for cell‐free massive MIMO systems
Abstract In cell‐free massive multiple‐input‐multiple‐output (CF‐MMIMO) systems, a massive number of access points, mastered by central processing units are distributed in a coverage area to serve much smaller number of user equipments (UEs) simultaneously over the same time/frequency resources.
