Massive MIMO (multiple-input multiple-output) is no longer a “wild” or “promising” concept
for future cellular networks—in 2018 it became a reality. Base stations (BSs) with 64 fully …

Massive multiple-input multiple-output (MIMO) is one of the most promising technologies for
the next generation of wireless communication networks because it has the potential to …

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 …

Compact arrays such as multiple antennas on a mobile terminal suffer from low efficiency
and high correlation between antenna signals. In the present paper, a simple and rigorous …

In recent years, a wealth of research has emerged addressing various aspects of mobile
communications signal processing. New applications and services are continually arising …

The primary objective of this thesis is to design advanced interference resilient schemes for
asynchronous slow frequency hopping wireless personal area networks (FH-WPAN) and …

Disclosed is a base station of a wireless communications system including an adaptive
