Co-Located vs Distributed vs Semi-Distributed MIMO: Measurement-Based Evaluation
Thomas Choi, Peng Luo, Akshay Ramesh +1
With the growing interest in cell-free massive multiple-input multiple-output (MIMO) systems, the benefits of single-antenna access points (APs) versus multi-antenna APs must be an…
Experimental Investigation of Frequency Domain Channel Extrapolation in Massive MIMO Systems for Zero-Feedback FDD
Thomas Choi, François Rottenberg, Jorge Gomez-Ponce +4
Estimating downlink (DL) channel state information (CSI) in frequency division duplex (FDD) massive multi-input multi-output (MIMO) systems generally requires downlink pilots and f…
Channel Extrapolation for FDD Massive MIMO: Procedure and Experimental Results
Thomas Choi, François Rottenberg, Jorge Gomez-Ponce +4
Application of massive multiple-input multiple-output (MIMO) systems to frequency division duplex (FDD) is challenging mainly due to the considerable overhead required for downlink…
