1. A method of processing a discrete time sampled sequence by a Tomlinson-Harashima Precoder (THP) comprising:

  • receiving a first discrete time sampled sequence by an L-tap Tomlinson-Harashima Precoder (THP);

    receiving a clock signal by said L-tap Tomlinson-Harashima Precoder (THP), said clock signal having a clock rate equal to one half the symbol rate of said discrete time sampled sequence;

    using L state variables to express one or more outputs of said L-tap Tomlinson-Harashima Precoder (THP);

    processing said first discrete time sampled sequence using L coefficients and said L state variables by clocking said first discrete time sampled sequence using said clock signal; and

    outputting a second discrete time sampled sequence by said L-tap Tomlinson-Harashima Precoder.
