MMSE-Optimal Sequential Processing for Cell-Free Massive MIMO With Radio Stripes
Zakir Hussain Shaik, Emil Björnson, Erik G. Larsson
Cell-free massive multiple-input-multiple-output (mMIMO) is an emerging technology for beyond 5G with its promising features such as higher spectral efficiency and superior spatial…
Max-Min Power Control in Downlink Massive MIMO with Distributed Antenna Arrays
Noman Akbar, Emil Bjornson, Nan Yang +1
In this paper, we investigate optimal downlink power allocation in massive multiple-input multiple-output (MIMO) networks with distributed antenna arrays (DAAs) under correlated an…
Reconfigurable Intelligent Surfaces: Three Myths and Two Critical Questions
Emil Björnson, Özgecan Özdogan, Erik G. Larsson
The search for physical-layer technologies that can play a key role in beyond-5G systems has started. One option is reconfigurable intelligent surfaces (RIS), which can collect wir…
Self-Learning Detector for the Cell-Free Massive MIMO Uplink: The Line-of-Sight Case
Giovanni Interdonato, Pål Frenger, Erik G. Larsson
The precoding in cell-free massive multiple-input multiple-output (MIMO) technology relies on accurate knowledge of channel responses between users (UEs) and access points (APs). O…
Cell-Free Massive MIMO With Radio Stripes and Sequential Uplink Processing
Zakir Hussain Shaik, Emil Björnson, Erik G. Larsson
Cell-free Massive MIMO (mMIMO) is envisaged to be a next-generation technology beyond 5G with its high spectral efficiency and superior spatial diversity as compared to that of con…
Performance Analysis of Quantized Uplink Massive MIMO-OFDM With Oversampling Under Adjacent Channel Interference
Ali Bulut Üçüncü, Emil Björnson, Håkan Johansson +2
Massive multiple-input multiple-output (MIMO) systems have attracted much attention lately due to the many advantages they provide over single-antenna systems. Owing to the many an…
