Abstract

We show that our new concatenated pipelining Tomlinson Harashima precoding (C-PIPTHP) can significantly improve the performance of downlink multiple-input multiple-output (MIMO) systems. We then combine this new scheme with the use of block diagonalization (BD) and Tomlinson Harashima precoding (THP) in a multiuser (MU) setting. In such a setting, BD is used to suppress interuser interference (IUI), and THP is used to pre-eliminate the interstream interference between streams. The new scheme proposed is called BD C-PIPTHP. Its improved processing speed and bit error rate (BER) performance over traditional BD THP MU-MIMO scheme are demonstrated via MATLAB simulations.
