Non-cooperative Limited Feedback Precoding with Subchannel Selection in MIMO Interference Channels

Abstract

In this letter, we propose a non-cooperative limited feedback precoding and subchannel selection scheme for non-reciprocal multiple-input multiple-output (MIMO) interference channels. At each iteration of the proposed scheme, each user updates its precoder selection for each subchannel and then chooses the predetermined number of sub-channels in a distributed and non-cooperative way. We present simulation results to verify the performance of the proposed scheme.
