In this paper, we analyze the spectral efficiency of multicell massive multiple-input-multiple-
output (MIMO) systems with downlink training and a new pilot contamination precoding …

Multi-antenna cache-aided wireless networks were thought to suffer from a severe feedback
bottleneck, since achieving the maximal Degrees-of-Freedom (DoF) performance required …

In this paper, we discuss the joint precoding with finite rate feedback in the so-called network
multiple-input multiple-output (MIMO) where the TXs share the knowledge of the data …

We consider a downlink cellular network where multi-antenna base stations (BSs) transmit
data to single-antenna users by using one of two linear precoding methods with limited …

In this paper, we analyze the ergodic sum-rate of a multi-cell downlink system with base
station (BS) cooperation using regularized zero-forcing (RZF) precoding. Our model …

Transmitter channel state information (CSIT) is indispensable for the spectral efficiency
gains offered by massive multiple-input multiple-output (MIMO) systems. In a frequency …

This paper characterizes the degree-of-freedom (DoF) regions for the multiuser vector
broadcast channel with periodic channel state information (CSI) feedback. As a part of the …

In this paper, we investigate the outage and ergodic capacity of downlink distributed
antenna systems (DAS) where each distributed antenna unit (DAU) has multiple antennas …

In this paper, we consider a two-cell interfering multiple-input multiple-output multiple access
channel (MIMO-MAC). We first investigate the multiplexing gain of such channel when users …

During the past decade, many wireless communication techniques have been developed to
achieve various goals such as higher data rate, more robust link quality, and higher number …
