MU-MIMO in LTE Systems [PDF]

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
A relatively recent idea of extending the benefits of MIMO systems to multiuser scenarios seems promising in the context of achieving high data rates envisioned for future cellular standards after 3G (3rd Generation).

Cross-Layer Optimization for Heterogeneous MU-MIMO/OFDMA Networks [PDF]

open access: yesSensors, 2021
To enable the full benefits from MU-MIMO (Multiuser-Multiple Input Multiple Output) and OFDMA (Orthogonal Frequency Division Multiple Access) to be achieved, the optimal use of these two technologies for a given set of network resources has been ...

An efficient binary salp swarm algorithm for user selection in multiuser MIMO antenna systems [PDF]

open access: yesScientific Reports
The past ten years have seen notable research activity and significant advancements in multiuser multiple-input multiple-output (MU-MIMO) antennas. An MU-MIMO antenna system must accommodate many subscribers without additional bandwidth or energy.

Gyre Precoding for MU-MIMO Systems

open access: yesIEEE Communications Letters, 2021
This work introduces Gyre Precoding (GP), a novel linear multi-user multiple-input multiple-output (MU-MIMO) precoding approach. GP performs rotations of the symbols of each spatial layer to optimize the precoding performance. To find the rotation angles, we propose a near-optimal, gradient descent–based low-complexity algorithm.

Performance Comparison for Single-User and Multi-User Network MIMO Cellular Systems with Power Management

open access: yesApplied Sciences, 2021
Cellular mobile systems aim at aggressive spectrum reuse to achieve high spectral efficiency. Unfortunately, this leads to unacceptable interference near cell borders.

LDPC Coded Multi-User Massive MIMO Systems With Low-Complexity Detection

open access: yesIEEE Access, 2022
We design a low-density parity-check (LDPC) coded multi-user (MU) massive multiple-input multiple-output (MIMO) system with an iterative joint detection and decoding (JDD) algorithm.

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

open access: yesIET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...
