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

The use of multiple antennas at base stations is a key component in the design of cellular
communication systems that can meet high-capacity demands in the downlink. Under ideal …

This paper provides an overview of multi-cell coordinated scheduling and multiple-input
multiple-output (MIMO) techniques in LTE. We first discuss single-user MIMO (SU-MIMO) …

We study the coordinated transmission problem in cooperative cellular networks where a
cluster of base stations forms a virtual cell to serve a mobile station (MS). The performance …

In this paper, we propose a series of novel coordination schemes for multi-cell downlink
communication. Starting from full base station (BS) coordination, we first propose a fully …

In this paper, we consider a multi-cell MISO downlink, where a multi-antenna base station
(BS) sends messages to its intended user, while a passive eavesdropper tries to intercept …

This letter studies a joint design of fronthaul compression and precoding for full-duplex (FD)
cloud radio access networks (C-RAN). In this system, each radio unit (RU) takes the role of …

We study a high throughput satellite system, where the feeder link uses free-space optical
(FSO) and the user link uses radio frequency (RF) communication. In particular, we first …

In this paper, we investigate a dynamic coordinated beamforming (CBF) problem to enhance
the sum rate of a massive multiple-input multiple-output (MIMO) cellular network. Although …

In this paper, we propose a new beamforming design to maximize energy efficiency (EE) for
multiple input single output interfering broadcast channels (IFBCs). Under this model, the EE …
