Achievable rates for Tomlinson-Harashima precoding
R.D. Wesel, J.M. Cioffi · 2002
The maximum achievable information rate of the zero-forcing Tomlinson-Harashima (1971, 1972) precoder (ZF-THP) is given exactly. Bounds are provided for the minimum mean square error (MMSE) THP. The performance of the THP is characterized on an example AWGN channel, and discussed for arbitrary channels.
