A flexible low-complexity robust THP approach for MISO downlinks with imperfect CSI

Abstract: Tomlinson-Harashima precoding (THP) is an attractive non-linear interference cancellation method for multipleinput multiple-output (MIMO) system with decentralized receivers. Compared to linear methods, it is able to achieve significant performance improvement while introduce negligible computational complexity increase. However, THP is sensitive to inevitable channel state information (CSI) errors at the transmitter in wireless communications. We statistically model the errors caused by channel estimation an… Show more
