Distributed Massive MIMO in Cellular Networks: Impact of Imperfect Hardware and Number of Oscillators
Emil Björnson, Michail Matthaiou, Antonios Pitarokoilis +1
Distributed massive multiple-input multiple-output (MIMO) combines the array gain of coherent MIMO processing with the proximity gains of distributed antenna setups. In this paper,…
Massive MIMO with Multi-cell MMSE Processing: Exploiting All Pilots for Interference Suppression
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new state-of-the-art multi-cell MMSE scheme is proposed for massive MIMO networks, which includes an uplink MMSE detector and a downlink MMSE precoder. The main no…
Cell-Free Massive MIMO: Uniformly Great Service For Everyone
Hien Quoc Ngo, Alexei Ashikhmin, Hong Yang +2
We consider the downlink of Cell-Free Massive MIMO systems, where a very large number of distributed access points (APs) simultaneously serve a much smaller number of users. Each A…
Blind Estimation of Effective Downlink Channel Gains in Massive MIMO
Hien Quoc Ngo, Erik G. Larsson
We consider the massive MIMO downlink with time-division duplex (TDD) operation and conjugate beamforming transmission. To reliably decode the desired signals, the users need to kn…
