Zero-forcing precoding (or ZF-precoding) is a spatial signal processing that nulls multiuser interference at the multiple antenna transmitter in [[wireless|wireless communications]]. Regularized zero-forcing precoding is enhanced processing to consider the impact on a background [[noise]] and unknown user [[interference]]<ref>{{cite journal|author=B. C. B. Peel, B. M. Hochwald, and A. L. Swindlehurst|title=A vector-perturbation technique for near-capacity multiantenna multiuser communication - Part I: channel inversion and regularization|journal=IEEE Trans. Commun.|pages=195–202|volume=53|date=Jan. 2005|doi=10.1109/TCOMM.2004.840638}}</ref>, where the background noise and the unknown user interference can be emphasized in the result of (known) interference signal nulling.
