Optimal Pilot and Payload Power Control in Single-Cell Massive MIMO Systems
Hei Victor Cheng, Emil Björnson, Erik G. Larsson
This paper considers the jointly optimal pilot and data power allocation in single-cell uplink massive multiple-input-multiple-output (MIMO) systems. Using the spectral efficiency…
Massive MIMO with Imperfect Channel Covariance Information
Emil Björnson, Luca Sanguinetti, Merouane Debbah
This work investigates the impact of imperfect statistical information in the uplink of massive MIMO systems. In particular, we first show why covariance information is needed and…
Spatio-Temporal Waveform Design for Multi-user Massive MIMO Downlink with 1-bit Receivers
Ahmet Gokceoglu, Emil Bjornson, Erik Larsson +1
Internet-of-Things (IoT) refers to a high-density network of low-cost low-bitrate terminals and sensors where also low energy consumption is one central feature. As the power-budge…
Pilot Contamination is Not a Fundamental Asymptotic Limitation in Massive MIMO
Emil Björnson, Jakob Hoydis, Luca Sanguinetti
Massive MIMO (multiple-input multiple-output) provides great improvements in spectral efficiency over legacy cellular networks, by coherent combining of the signals over a large an…
Performance Analysis of Multi-User Massive MIMO Downlink under Channel Non-Reciprocity and Imperfect CSI
Orod Raeesi, Ahmet Gokceoglu, Yaning Zou +2
This paper analyzes the performance of linearly precoded time division duplex based multi-user massive MIMO downlink system under joint impacts of channel non-reciprocity (NRC) and…
Multi-Cell Massive MIMO Performance with Double Scattering Channels
Trinh Van Chien, Emil Björnson, Erik G. Larsson
This paper investigates the spectral efficiency (SE) of multi-cell Massive Multi-Input Multi-Output (MIMO) using different channel models. Prior works have derived closed-form SE b…
