We investigate the performance of multi-user multiple-antenna downlink systems in which a
base station (BS) serves multiple users via a shared wireless medium. In order to fully …

In this work, two efficient low complexity Antenna Selection (AS) algorithms are proposed for
downlink Multi-User (MU) Massive Multiple-Input Multiple-Output (M-MIMO) systems with …

This paper presents a performance analysis of two distinct techniques for antenna selection
and precoding in downlink multi-user massive multiple-input single-output systems with …

Large number of antennas and radio frequency (RF) chains at the base stations (BSs) lead
to high energy consumption in massive MIMO systems. Thus, how to improve the energy …

Recent years have witnessed unprecedented growth in wireless networks in terms of both
data traffic and number of connected devices. How to support this fast increasing demand for …

Antenna selection is a promising solution to reduce the system cost, specially for Massive
MIMO systems with large scale antennas. In this paper, we consider the antenna selection …

Massive Multiple-Input Multiple-Output (M-MIMO) is a state of the art technology in wireless
communications, where hundreds of antennas are exploited at the base station (BS) to serve …
