SINR analysis for V-BLAST with ordered MMSE-SIC detection

A new way to determine the exact layer-wise SINR distribution for V-BLAST with successive interference cancellation at the receiver is presented. In contrast to previous publications, we do not restrict to zero-forcing, but also consider minimum mean square error interference suppression. It is shown analytically that an optimized detection order has an even larger impact in this case. Numerical examples provide deeper insights into the underlying effects.
