Survey of Large-Scale MIMO Systems [PDF]
IEEE Communications Surveys and Tutorials, 2015 The escalating teletraffic growth imposed by the proliferation of smartphones and tablet computers outstrips the capacity increase of wireless communications networks. Furthermore, it results in substantially increased carbon dioxide emissions. As a powerful countermeasure, in the case of full-rank channel matrices, MIMO techniques are potentially ...

Non-Stationarities in Extra-Large-Scale Massive MIMO [PDF]
IEEE Wireless Communications, 2020 Massive MIMO, a key technology for increasing area spectral efficiency in cellular systems, was developed assuming moderately sized apertures. In this paper, we argue that massive MIMO systems behave differently in large-scale regimes due to spatial non-stationarity.

Fifty Years of MIMO Detection: The Road to Large-Scale MIMOs [PDF]
IEEE Communications Surveys and Tutorials, 2015 The emerging massive/large-scale MIMO (LS-MIMO) systems relying on very large antenna arrays have become a hot topic of wireless communications. Compared to the LTE based 4G mobile communication system that allows for up to 8 antenna elements at the base station (BS), the LS-MIMO system entails an unprecedented number of antennas, say 100 or more, at ...

Beam Grouping Based RS Resource Reuse and De-Contamination in Large Scale MIMO Systems
Applied Sciences, 2017 It is well known that large scale multiple-input multiple-output (LS-MIMO) systems are very attractive technology to increase both spectral efficiency (SE) and energy efficiency (EE). However, one of big obstacles to the realization of the LS-MIMO system
