Finite Rate Feedback Design for Multiple Transmit Antennas

Most practical systems employ a feedback channel to convey the channel state information to the transmitter. In this work, we address the problem of designing feedback, with constraints on the feedback rate, for a multiple transmit antenna system employing transmit beamforming with a single receiver antenna. The important contribution of this work is a design criterion for construction of a finite set of beamformers which leads to near optimal outage performance.
