This paper provides upper and lower bounds on the information rates achievable with a minimum mean square error (MMSE) Tomlinson-Harishima precoder (THP) assuming ideal interleaving. We also give an exact formula for zero-forcing (ZF) THP achievable information rates. At high SNR, the performance of the MMSE-THP and the ZF-THP identically suffer only the 2.55 bit or 1.53 dB -shaping" loss from capacity. At low SNR, shaping loss is negligible, but the THP systems again do not achieve capacity… CONTINUE READING
