Abstract

In this letter, we consider a probabilistic limited feedback precoding in MIMO interference channels. The probabilistic use of precoders in the codebook is modeled as a mixed strategy in a nonzero-sum game. The sum rate of mixed strategy Nash equilibrium (NE) and the maximum achievable sum rate of the probabilistic limited feedback precoding are derived in a two-user MIMO interference channel. For a distributed realization of probabilistic limited feedback precoding, we also propose a distributed limited feedback precoding scheme for use in K-user MIMO interference channels.
