Jamming Detection in Massive MIMO Systems
Hossein Akhlaghpasand, S. Mohammad Razavizadeh, Emil Björnson +1
This paper considers the physical layer security of a pilot-based massive multiple-input multiple-output (MaMIMO) system in presence of a multi-antenna jammer. To improve security…
Performance of In-band Transmission of System Information in Massive MIMO Systems
Marcus Karlsson, Emil Björnson, Erik G. Larsson
We consider transmission of system information in massive MIMO. This information needs to be reliably delivered to inactive users in the cell without any channel state information…
Performance Analysis of NOMA in Training Based Multiuser MIMO Systems
Hei Victor Cheng, Emil Björnson, Erik G. Larsson
This paper considers the use of NOMA in multiuser MIMO systems in practical scenarios where CSI is acquired through pilot signaling. A new NOMA scheme that uses shared pilots is pr…
Joint Transmit and Circuit Power Minimization in Massive MIMO with Downlink SINR Constraints: When to Turn on Massive MIMO?
Kamil Senel, Emil Björnson, Erik G. Larsson
In this work, we consider the downlink of a multi-cell multiple-input multiple-output (MIMO) system and find the jointly optimal number of base station (BS) antennas and transmissi…
BER Performance Analysis of Coarse Quantized Uplink Massive MIMO
Azad Azizzadeh, Reza Mohammadkhani, Seyed Vahab Al-Din Makki +1
Having lower quantization resolution, has been introduced in the literature, as a solution to reduce the power consumption of massive MIMO and millimeter wave MIMO systems. In this…
Channel Hardening and Favorable Propagation in Cell-Free Massive MIMO with Stochastic Geometry
Zheng Chen, Emil Björnson
Cell-Free (CF) Massive MIMO is an alternative topology for future wireless networks, where a large number of single-antenna access points (APs) are distributed over the coverage ar…
