Energy Efficiency of Massive MIMO: Coping with Daily Load Variation
M M Aftab Hossain, Cicek Cavdar, Emil Björnson +1
Massive MIMO is a promising technique to meet the exponential growth of mobile traffic demand. However, contrary to the current systems, energy consumption of next generation netwo…
Uplink Pilot and Data Power Control for Single Cell Massive MIMO Systems with MRC
Hei Victor Cheng, Emil Björnson, Erik G. Larsson
This paper considers the jointly optimal pilot and data power allocation in single cell uplink massive MIMO systems. A closed form solution for the optimal length of the training i…
A Multi-cell MMSE Precoder for Massive MIMO Systems and New Large System Analysis
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new multi-cell MMSE precoder is proposed for massive MIMO systems. We consider a multi-cell network where each cell has users and orthogonal pilot sequence…
A Multi-cell MMSE Detector for Massive MIMO Systems and New Large System Analysis
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new multi-cell MMSE detector is proposed for massive MIMO systems. Let and denote the number of users in each cell and the number of available pilot sequen…
Subverting Massive MIMO by Smart Jamming
Hessam Pirzadeh, S. Mohammad Razavizadeh, Emil Björnson
We consider uplink transmission of a massive multi-user multiple-input multiple-output (MU-MIMO) system in the presence of a smart jammer. The jammer aims to degrade the sum spectr…
Pilot Clustering in Asymmetric Massive MIMO Networks
Rami Mochaourab, Emil Björnson, Mats Bengtsson
We consider the uplink of a cellular massive MIMO network. Since the spectral efficiency of these networks is limited by pilot contamination, the pilot allocation across cells is o…
