Abstract
In this paper, we investigate the effect of precoding ordering on systems with successive interference cancellation for multiple-input multiple-output (MIMO) ,i.e., Tomlinson-Harashima precoding (THP). Based on the well known QR decomposition, a simple precoding ordering scheme based on a per-layer mean square error (M SE) criterion of the diagonal entries of the R-factor is proposed. In addition, an efficient point-to-point communications while in [8,9] transmit feed forward filter is used, allowing point-to-multi-point communications (downlink scenarios) with decentralised and noncooperatives implereceivers.
