Fundamental Asymptotic Behavior of (Two-User) Distributed Massive MIMO
Luca Sanguinetti, Emil Bjornson, Jakob Hoydis
This paper considers the uplink of a distributed Massive MIMO network where base stations (BSs), each equipped with antennas, receive data from users. We study the as…
Power Control for D2D Underlay in Multi-cell Massive MIMO Networks
Amin Ghazanfari, Emil Björnson, Erik G. Larsson
This paper proposes a new power control and pilot allocation scheme for device-to-device (D2D) communication underlaying a multi-cell massive MIMO system. In this scheme, the cellu…
Hardware Distortion Correlation Has Negligible Impact on UL Massive MIMO Spectral Efficiency
Emil Björnson, Luca Sanguinetti, Jakob Hoydis
This paper analyzes how the distortion created by hardware impairments in a multiple-antenna base station affects the uplink spectral efficiency (SE), with focus on Massive MIMO. T…
Downlink Spectral Efficiency of Cell-Free Massive MIMO with Full-Pilot Zero-Forcing
Giovanni Interdonato, Marcus Karlsson, Emil Björnson +1
Cell-free Massive multiple-input multiple-output (MIMO) ensures ubiquitous communication at high spectral efficiency (SE) thanks to increased macro-diversity as compared cellular c…
What Role Can NOMA Play in Massive MIMO?
Kamil Senel, Hei Victor Cheng, Emil Björnson +1
This paper seeks to answer a simple but fundamental question: What role can NOMA play in massive MIMO? It is well-established that power-domain non-orthogonal multiple access (NOMA…
Humans and Machines can be Jointly Spatially Multiplexed by Massive MIMO
Kamil Senel, Emil Björnson, Erik G. Larsson
Future cellular networks are expected to support new communication paradigms such as machine-type communication (MTC) services along with conventional human-type communication (HTC…
