Enhanced Channel Estimation in Massive MIMO via Coordinated Pilot Design
Kaiming Shen, Hei Victor Cheng, Xihan Chen +2
Pilot contamination is a limiting factor in multicell massive multiple-input multiple-output (MIMO) systems because it can severely impair channel estimation. Prior works have sugg…
