This paper addresses interference management in downlink (DL) transmission of a multi-
user multiple-input multiple-output (MU-MIMO) system in time division duplex (TDD) mode. A …

Separating highly correlated users can reduce the loss caused by spatial correlation (SC) in
multiuser multiple‐input multiple‐output (MU‐MIMO) systems. However, few accurate …

In this work, we investigate the sum-rate performance of multicell and cell-free massive

In this paper, we consider a time-division duplex (TDD) multi-cell massive MIMO system.
Channel estimation is hampered by pilot contamination from neighbouring cells. We …

This paper proposes an efficient downlink multi-user MIMO (MU-MIMO) scheme for multiple
antenna transmission systems comprised of reconfigurable antenna (RA) elements. MU …

Practical precoding schemes inevitably have to deal with the problem of imperfect, rather
than ideal, channel state information at the transmitter (CSIT). This impairment permeates all …

When a MIMO wireless channel matrix H is rank deficient, it is often required to select a
submatrix Hp ϵ H such that the columns of Hp lie close to the optimal subspace that …
