  In this paper, we study the interference cancellation capabilities of
receivers and transmitters in multiple-input-multiple-output (MIMO) systems
using theoretical calculations and numerical simulations in Quadriga. We study
so-called Reduced Channel Zero-Forcing (RCZF) class of precoding as well as
Minimum MSE Interference Rejection Combiner (MMSE-IRC) and QR Maximum
Likelihood Detection (QR-MLD) receivers. Based on very simple but extremely
useful algebraic manipulations, their asymptotical equivalence is proven
analytically and demonstrated via simulations. Our theoretical and experimental
results confirm that MMSE-IRC and QR-MLD receivers in combination with the RCZF
precoding provide complete interference suppression asymptotically.
