Remarkable research activities and major advances have been occurred over the past
decade in multiuser multiple-input multiple-output (MU-MIMO) systems. Several …

In TD-LTE-A system, dual layer beamforming is introduced to improve throughput of specific
users with high SINRs. In order to solve the problem of resource allocation for multi-user …

As a conventional metric, spectrum efficiency has been investigated widely in
communication systems due to the limited bandwidth resources and increasing subscriber …

Joint user selection algorithm and fully digital geometric mean decomposition (GMD)-based
precoding scheme is considered in this paper for single radio frequency (RF) space …

In this paper, we tackle the problem of semidistributed user selection with distributed linear
precoding for sum-rate maximization in multiuser multicell systems. A set of adjacent base …

In recent years, the demand for higher communication capacity in wireless networks has led
to the development of massive multiple-input multiple-output (MIMO) systems. Al-though …

The 5G wireless channel in the high-speed rail scene has the characteristics of fast time-
varying and double selection, that is, frequency selectivity and time selectivity. The change …

Conventional multi-user scheduling schemes are designed based on instantaneous
channel state information (CSI), indicating that decisions must be made every transmission …

For multiuser massive MIMO systems, the acquisition and utilization of statistical channel
information is very important. In this paper, we first adopt PASTd algorithm to track the uplink …

In this work we present a unified treatment on the most common metrics used in the utility
function of state-of-the-art user selection algorithms for sum rate maximization in MISO …
