Channel state information (CSI) is essential in massive multiple-input mulitple-output (MIMO)
systems. However, most of the literature focuses on frequency-flat channel estimation; in a …

Motivated by recent developments in time-division duplex massive multiple-input multiple-
output (MIMO) systems, this paper investigates semi-blind channel estimation for multiuser …

This paper considers channel estimation and system performance for the uplink of a single-
cell massive multiple-input multiple-output system. Each receiver antenna of the base station …

This paper addresses downlink channel estimation for frequency division duplex multi-user
massive multiple-input multiple-output systems. Suppose that a base station communicates …

In this paper we study the channel estimation problem for a CP-OFDM based hybrid analog-
digital massive MIMO system. In contrast to a conventional MIMO system, two additional …

Channel estimation for the downlink of frequency division duplex (FDD) massive multiple-
input-multiple output (MIMO) systems is well known to generate a large overhead as the …

We study the problem of semi-blind channel estimation and symbol detection in the uplink of
multi-cell massive MIMO (multi-input multi-output) systems with spatially correlated time …

We study downlink channel estimation in a multi-cell Massive multiple-input multiple-output
(MIMO) system operating in time-division duplex. The users must know their effective …

As the array dimension of massive MIMO systems increases to unprecedented levels, two
problems occur. First, the spatial stationarity assumption along the antenna elements is no …
