Towards a Realistic Assessment of Multiple Antenna HCNs: Residual Additive Transceiver Hardware Impairments and Channel Aging
Anastasios Papazafeiropoulos, Tharm Ratnarajah
Given the critical dependence of broadcast channels by the accuracy of channel state information at the transmitter (CSIT), we develop a general downlink model with zero-forcing (Z…
Mitigation of Phase Noise in Massive MIMO Systems: A Rate-Splitting Approach
Anastasios Papazafeiropoulos, Bruno Clerckx, Tharm Ratnarajah
This work encompasses Rate-Splitting (RS), providing significant benefits in multi-user settings in the context of huge degrees of freedom promised by massive Multiple-Input Multip…
Impact of General Channel Aging Conditions on the Downlink Performance of Massive MIMO
Anastasios K. Papazafeiropoulos
Recent works have identified massive multiple-input-multiple-output (MIMO) as a key technology for achieving substantial gains in spectral and energy efficiency. Additionally, the…
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…
