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…
Uplink Performance of Conventional and Massive MIMO Cellular Systems with Delayed CSIT
Anastasios K. Papazafeiropoulos, Hien Quoc Ngo, Tharm Ratnarajah
Massive multiple-input multiple-output (MIMO) networks, where the base stations (BSs) are equipped with large number of antennas and serve a number of users simultaneously, are ver…
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…
