Massive multiple-input multiple-output (MIMO) wireless communications refers to the idea
equipping cellular base stations (BSs) with a very large number of antennas, and has been …

Multi-user MIMO offers big advantages over conventional point-to-point MIMO: it works with
cheap single-antenna terminals, a rich scattering environment is not required, and resource …

The last ten years have seen a massive growth in the number of connected wireless
devices. Billions of devices are connected and managed by wireless networks. At the same …

Massive multiple‐input multiple‐output technology has been considered a breakthrough in
wireless communication systems. It consists of equipping a base station with a large number …

Since the seminal paper by Marzetta from 2010, Massive MIMO has changed from being a
theoretical concept with an infinite number of antennas to a practical technology. The key …

Next-generation wireless networks aim at providing substantial improvements in spectral
efficiency (SE) and energy efficiency (EE). Massive MIMO has been proved to be a viable …

Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is
achieved by allowing the number of antennas and RF chains to grow very large. However …

Telecommunications have grown to be a pillar to a functional society and the urge for
