Near-Field Range-Angle Estimation and Power Allocation for Cell-Free Massive MIMO ISAC With Extremely Large Arrays
The deployment of extremely large-scale antenna arrays (ELAAs) at the access points (APs) of cell-free (CF) massive multiple-input multiple-output (MIMO) networks extends the near-field Rayleigh boundary to several hundred metres, invalidating the conventional plane-wave assumption for both communications and radar sen...
