ABSTRACT
A method to design receive beamforming vectors with user selection is proposed for the multiuser Tomlinson-Harashima precoding, where each user is equipped with multiple antennas. The method exploits the relationship between LQ decomposition and Gram-Schmidt process to jointly optimize the receive beamforming vectors of users. Furthermore, a new approach is presented to reduce the amount of information required to send the beamforming vectors from the base station to users. Simulation results are provided to support the advantages of the proposed schemes.

Tomlinson-Harashima Precoding for Multiuser MIMO Downlink with Imperfect Channel State Information
ICMTMA '11: Proceedings of the 2011 Third International Conference on Measuring Technology and Mechatronics Automation - Volume 03Most contributions on nonlinear Tomlinson-Harashima precoding (THP) assume complete channel state information (CSI) at the transmitter. However, complete CSI is not available in many wireless systems, and the conventional THP is sensitive to channel ...
