Gyre Precoding for MU-MIMO Systems
IEEE Communications Letters, 2021 This work introduces Gyre Precoding (GP), a novel linear multi-user multiple-input multiple-output (MU-MIMO) precoding approach. GP performs rotations of the symbols of each spatial layer to optimize the precoding performance. To find the rotation angles, we propose a near-optimal, gradient descent–based low-complexity algorithm.

Mode Switching for the Multi-Antenna Broadcast Channel Based on Delay and Channel Quantization
EURASIP Journal on Advances in Signal Processing, 2009 Imperfect channel state information degrades the performance of multiple-input multiple-output (MIMO) communications; its effects on single-user (SU) and multiuser (MU) MIMO transmissions are quite different.
