Semi-dynamic pilot allocation based on graph coloring in massive MIMO systems

Show other versions (1)

To alleviate the performance loss caused by pilot contamination in massive multiple-input multiple-output (MIMO) systems,a semi-dynamic pilot allocation scheme based on graph coloring was proposed.Firstly,a pilot reuse threshold was derived for users.Then,based on the pilot reuse threshold,users of...
