A modified precoding scheme for MIMO downlink channel with imperfect CSIT

Abstract

In this paper, we consider the multiuser MIMO downlink channel with multiple antennas at both the base station and the users. We concentrate on the case where the transmitter has imperfect channel state information due to estimation error and feedback delay. A channel modification matrix and a scalar factor based on minimum mean square error criterion are… (More)
