We consider the channel estimation problem in point-to-point reconfigurable intelligent
surface (RIS)-aided millimeter-wave (mmWave) MIMO systems. By exploiting the low-rank …

In this work, we consider both channel estimation and reflection coefficient design problems
in point-to-point reconfigurable intelligent surface (RIS)-aided millimeter-wave (mmWave) …

In this article, we consider the channel estimation problem in sub-6 GHz uplink wideband
multiple-input multiple-output (MIMO)-orthogonal frequency-division multiplexing (OFDM) …

Wireless networks are incorporating higher frequency bands and higher bandwidths by
exploiting MIMO technology with large arrays. These large arrays and bandwidths enable …

Seit den späten 1990er Jahren wurden massive MIMO (multiple-input multiple-output)
Systeme vorgeschlagen, um die erreichbaren Datenraten in drahtlosen …

This chapter addresses sparse signal reconstruction under various types of structural side
constraints with applications in multi-antenna systems. Side constraints may result from prior …

In this paper, the Massive multiple-input multiple-output systems which have lately gotten a
lot of press because they can harness a lot of antennas at the base station (BS), maybe even …
