(TDD)/frequency division duplex (FDD) massive multiple-input-multiple-output (MIMO) …

Massive multiple-input multiple-output (massive MIMO) has been studied to improve the
throughput in cellular communication systems via spatial degrees of freedom and array gain …

The millimeter-wave (mm-wave) massive multiple-input multiple-output (MIMO) system has
gained much attention for its considerable improvement in system throughput. However, the …

In a cell-free (CF) massive MIMO architecture a very large number of distributed access
points (APs) simultaneously and jointly serves a much smaller number of mobile stations …

This paper studies a variant of hybrid beamforming, namely, hybrid beamforming with
selection (HBwS), as an attractive solution to reduce the hardware cost of multiuser Massive …

The conventional full radio frequency (RF) configuration appears to be unfeasible in
massive multiple-input-multiple-output (MIMO) systems due to the still-exorbitant energy …
