Abstract :
Based on a multi-branch (MB) strategy, a new Tomlinson-Harashima precoding (THP) structure is proposed for single-user multiple-input multiple-output (SU-MIMO) systems, which offers a significant performance improvement compared to the conventional THP reported in the literature. The parallelized multiple branch signals are generated at the transmit side according to the pre-designed transmit patterns. An appropriate measurement metric is developed to select the best branch for transmission. Simulation results show that the proposed MB-THP precoder has a better bit error rate (BER) performance than the conventional THP.
