Massive MIMO with Multi-Antenna Users: When are Additional User Antennas Beneficial?
Xueru Li, Emil Björnson, Shidong Zhou +1
We analyze the performance of massive MIMO systems with -antenna users. The benefit is that streams can be multiplexed per user, at the price of increasing the channel estim…
Capacity Analysis for Spatially Non-wide Sense Stationary Uplink Massive MIMO Systems
Xueru Li, Shidong Zhou, Emil Björnson +1
Channel measurements show that significant spatially non-wide-sense-stationary characteristics rise in massive MIMO channels. Notable parameter variations are experienced along the…
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…
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…
