In this paper, we study the capacity-achieving input covariance matrices for the multiuser
multiple-input multiple-output (MIMO) uplink channel under jointly-correlated Rician fading …

Analytical expressions to approximate the expected per-user signal-to-interference-plus-
noise-ratio (SINR) and ergodic sum-rate of a multiuser multiple-input-multiple-output system …

In this paper, we study the achievable ergodic sum-rate of multiuser multiple-input multiple-
output downlink systems in Rician fading channels. We first derive a lower bound on the …

Presence of multiple antennas on both sides of a communication channel promises
significant improvements in system throughput and power efficiency. In effect, a new class of …

This paper investigates a reconfigurable intelligent surface (RIS)-aided multi-user multiple-
input multiple-output (MIMO) system by considering only the statistical channel state …

In this paper, we focus on the downlink ergodic sum rate of a single-cell large-scale
multiuser MIMO system in which the base station employs N antennas to communicate with …

This work focuses on the downlink and uplink of large-scale single-cell multiuser multiple-
input multiple-output systems in which the base station (BS) endowed with M antennas …

No systematic procedure for tightly bounding the average capacity of multiple-input-multiple-
output (MIMO) correlated Rician fading channels is available in the literature. In addition to …

Closed-form approximations of the expected per-terminal signal-to-interference-plus-noise-
ratio (SINR) and ergodic sum spectral efficiency of a multiuser multiple-input multiple-output …

Antenna selection (AS) is a promising technology to substantially reduce the complexity of
massive multiple-input multiple-output (MIMO) systems. However, spatial correlation and …
