  Filter bank based multicarrier with Offset-QAM systems (FBMC/OQAM) are strong
candidates for the waveform of future 5-th generation (5G) wireless standards.
These systems can achieve maximum spectral efficiency compared to other
multicarrier schemes, particularly in highly frequency selective propagation
conditions. In this case a multi-tap, fractionally spaced equalizer or precoder
needs to be inserted in each subcarrier at the receiver or transmitter side to
compensate inter-symbol interference (ISI) and inter-carrier interference
(ICI). In this paper we propose a new Tomlinson-Harashima precoder (THP) design
for FBMC/OQAM based on the mean squared error (MSE) duality from a minimum MSE
(MMSE) designed decision feedback equalizer (DFE).
