Uplink Coverage of User-Centric Cell-Free Networks Under Pilot Contamination and Spatial Correlation: A Tractable Stochastic Geometry Analysis
Cell-free massive multiple-input multiple-output (MIMO) has been recognized as a key technology of sixth-generation mobile systems. However, its performance is limited by pilot contamination, spatial antenna correlation, and path loss. This paper studies the uplink coverage probability of a user-centric cell-free netwo...
