Subspace-Enhanced Data-Aided Iterative Channel Estimation for Cell-Free Massive MIMO Systems

Cell-free massive multiple-input multiple-output (CF m-MIMO) is a pivotal wireless transmission technology for sixthgeneration (6G) communication systems. However, as the density of user equipment (UE) increases, the sharing of limited orthogonal pilot resources among a large number of UEs leads to severe pilot contami...
