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…
Downlink Training in Cell-Free Massive MIMO: A Blessing in Disguise
Giovanni Interdonato, Hien Quoc Ngo, Pål Frenger +1
Cell-free Massive MIMO (multiple-input multiple-output) refers to a distributed Massive MIMO system where all the access points (APs) cooperate to coherently serve all the user equ…
Scalability Aspects of Cell-Free Massive MIMO
Giovanni Interdonato, Pål Frenger, Erik G. Larsson
Ubiquitous cell-free massive MIMO (multiple-input multiple-output) combines massive MIMO technology and user-centric transmission in a distributed architecture. All the access poin…
Utility-based Downlink Pilot Assignment in Cell-Free Massive MIMO
Giovanni Interdonato, Pål Frenger, Erik G. Larsson
We propose a strategy for orthogonal downlink pilot assignment in cell-free massive MIMO (multiple-input multiple-output) that exploits knowledge of the channel state information,…
Ubiquitous Cell-Free Massive MIMO Communications
Giovanni Interdonato, Emil Björnson, Hien Quoc Ngo +2
Since the first cellular networks were trialled in the 1970s, we have witnessed an incredible wireless revolution. From 1G to 4G, the massive traffic growth has been managed by a c…
On the Performance of Cell-Free Massive MIMO with Short-Term Power Constraints
Giovanni Interdonato, Hien Quoc Ngo, Erik G. Larsson +1
In this paper we consider a time-division duplex cell-free massive multiple-input multiple-output (MIMO) system where many distributed access points (APs) simultaneously serve many…
How Much Do Downlink Pilots Improve Cell-Free Massive MIMO?
Giovanni Interdonato, Hien Quoc Ngo, Erik G. Larsson +1
In this paper, we analyze the benefits of including downlink pilots in a cell-free massive MIMO system. We derive an approximate per-user achievable downlink rate for conjugate bea…
