Max-Min Multi-Cell Aware Precoding and Power Allocation for Downlink Massive MIMO Systems
Shahram Zarei, Jocelyn Aulin, Wolfgang Gerstacker +1
We propose a max-min multi-cell aware regularized zero-forcing (Max-Min MCA-RZF) precoding and power allocation scheme for downlink multi-cell massive multiple-input multiple-outpu…
Low-Complexity Hybrid Linear/Tomlinson-Harashima Precoding for Downlink Large-Scale MU-MIMO Systems
Shahram Zarei, Wolfgang Gerstacker, Robert Schober
In this paper, we propose a novel low-complexity hybrid linear/Tomlinson-Harashima precoder (H-L-THP) for downlink large-scale multiuser multiple-input multiple-output (MU-MIMO) sy…
I/Q Imbalance Aware Widely-Linear Receiver for Uplink Multi-Cell Massive MIMO Systems
Shahram Zarei, Wolfgang Gerstacker, Jocelyn Aulin +1
In-phase/quadrature-phase (I/Q) imbalance is one of the most important hardware impairments in communication systems. It arises in the analogue parts of direct conversion radio fre…
Low-Complexity Widely-Linear Precoding for Downlink Large-Scale MU-MISO Systems
Shahram Zarei, Wolfgang Gerstacker, Robert Schober
In this letter, we present a widely-linear minimum mean square error (WL-MMSE) precoding scheme employing real-valued transmit symbols for downlink large-scale multi-user multiple-…
