Abstract
MIMO precoding matches the transmission to channel conditions in order to reduce or eliminate interference at the receiver. In this paper, we are interested in the case where the receiver is also equipped with a linear processor, specifically a ZF filter. We analyze the effect of the ZF receive filter on the performance of a variety of MIMO precoders. It is shown that receive-side ZF equalization can remove the error floors that sometimes appear with regularized zero-forcing precoding and matched-filter precoding.
