Massive MIMO is a disruptive technology that was born more than a decade ago, and that
has been adopted as an integral part of the 5G standard. Without its many advantages, the …

In the past ten years, there have been tremendous research progresses on massive MIMO
systems, most of which stand from the communications viewpoint. A new trend to investigate …

This paper proposes a unified transmission strategy for multiuser time division duplex
(TDD)/frequency division duplex (FDD) massive multiple-input-multiple-output (MIMO) …

This paper studies the impact of hardware mismatch (11M) between the base station (BS)
and the user equipment (UE) in the downlink (DL) of large-scale antenna systems. Analytical …

In this paper, we introduce a new spatial spectrum-sharing strategy for massive multiple-
input multiple-output (MIMO) cognitive radio (CR) systems. Different from the conventional …

The demand for wireless connectivity has grown exponentially over the last years. By 2030
there should be around 17 billion of mobile-connected devices, with monthly data traffic in …

This paper proposes a practical channel estimation for 60-GHz indoor systems with the
massive uniform rectangular array at base station. Through antenna array theory, the …

We propose iterative detection and decoding (IDD) algorithms with low-density parity-check
(LDPC) codes for multiple-input multiple-output (MIMO) systems operating in block-fading …

In this paper, we study widely linear precoding techniques to mitigate in-phase/quadrature-
phase (IQ) imbalance (IQI) in the downlink of large-scale multiple-input multiple-output …

Small satellites, or CubeSats, are envisioned as a promising solution for future satellite
communication networks because of their low costs and short deployment cycle. Currently …
