Coordinate Tomlinson-Harashima Precoding Design for Overloaded Multi-user MIMO Systems
K. Zu, R. C. de Lamare
Tomlinson-Harashima precoding (THP) is a nonlinear processing technique employed at the transmit side to implement the concept of dirty paper coding (DPC). The perform of THP, howe…

Multi-User Flexible Coordinated Beamforming using Lattice Reduction for Massive MIMO Systems
K. Zu, R. C. de Lamare
The application of precoding algorithms in multi-user massive multiple-input multiple-output (MU-Massive-MIMO) systems is restricted by the dimensionality constraint that the numbe…

Successive Optimization Tomlinson-Harashima Precoding Strategies for Physical-Layer Security in Wireless Networks
X. Luo, R. C. de Lamare, K. Zu
In this paper, we propose successive optimization non-linear precoding strategies for physical-layer security in wireless networks. We also investigate different precoding techniqu…
