In this paper, we investigate security and energy efficiency of multicast communication in
cognitive satellite terrestrial networks. To achieve high spectrum efficiency and low …

Due to the limited ability of a single unmanned aerial vehicle (UAV), group unmanned aerial
vehicles (UAVs) have attracted more attention in communication and radar fields. The use of …

The development of space-based Internet of Things is limited by insufficient allocable
frequency resources and low spectrum utilization. To meet the demand for massive access …

Interference cancellation in hybrid precoded downlink massive multi-user multi-input multi-
output (MU-MIMO) systems, eg, block diagonalization (BD), has a complexity that increases …

In this work we study different scheduling problems in the downlink of a Frequency Division
Duplex multiuser wireless system that employs a hybrid precoding antenna architecture for …

A future millimeter-wave (mmWave) massive multiple-input and multiple-output (MIMO)
system may serve hundreds or thousands of users at the same time; thus, research on …

Fifth-generation wireless networks require energy efficient and seamless connectivity, and it
is offered by massive MIMO system using spatial multiplexing with unprecedented array …

This work studies the problems of routing, beam‐channel selection, space/time division
multiple accessing, and admission control for multi‐rate wireless networks equipped with …

This paper studies the joint scheduling and power allocation for uplink multiuser multi-input
multi-output (MU-MIMO) orthogonal frequency division multiple access (OFDMA) systems …
