Region-Based Constellation Designs for Constructive Interference Precoding in MU-MIMO
Yupeng Zheng, Chunmei Xu, Jinfei Wang +2
The performance of constructive interference precoding (CIP) for multi-user multi-antenna (MU-MIMO) systems is governed by the structure of the constructive interference (CI) regio…

Accelerating Iteratively Linear Detectors in Multi-User (ELAA-)MIMO Systems with UW-SVD
Jiuyu Liu, Yi Ma, Jinfei Wang +1
Current iterative multiple-input multiple-output (MIMO) detectors suffer from slow convergence when the wireless channel is ill-conditioned. The ill-conditioning is mainly caused b…
