Massive MIMO with Optimal Power and Training Duration Allocation
Hien Quoc Ngo, Michail Matthaiou, Erik G. Larsson
We consider the uplink of massive multicell multiple-input multiple-output systems, where the base stations (BSs), equipped with massive arrays, serve simultaneously several termin…
Massive MIMO with Non-Ideal Arbitrary Arrays: Hardware Scaling Laws and Circuit-Aware Design
Emil Björnson, Michail Matthaiou, Mérouane Debbah
Massive multiple-input multiple-output (MIMO) systems are cellular networks where the base stations (BSs) are equipped with unconventionally many antennas, deployed on co-located o…
Energy Efficiency Optimization in Hardware-Constrained Large-Scale MIMO Systems
Xinlin Zhang, Michail Matthaiou, Mikael Coldrey +2
Large-scale multiple-input multiple-output (MIMO) communication systems can bring substantial improvement in spectral efficiency and/or energy efficiency, due to the excessive degr…
Impact of Residual Transmit RF Impairments on Training-Based MIMO Systems
Xinlin Zhang, Michail Matthaiou, Mikael Coldrey +1
Radio-frequency (RF) impairments, that exist intimately in wireless communications systems, can severely degrade the performance of traditional multiple-input multiple-output (MIMO…
On the MIMO Capacity with Residual Transceiver Hardware Impairments
Xinlin Zhang, Michail Matthaiou, Emil Björnson +2
Radio-frequency (RF) impairments in the transceiver hardware of communication systems (e.g., phase noise (PN), high power amplifier (HPA) nonlinearities, or in-phase/quadrature-pha…
Power Scaling of Uplink Massive MIMO Systems with Arbitrary-Rank Channel Means
Qi Zhang, Shi Jin, Kai-Kit Wong +2
This paper investigates the uplink achievable rates of massive multiple-input multiple-output (MIMO) antenna systems in Ricean fading channels, using maximal-ratio combining (MRC)…
