Beamformer Design with Feedback Rate Constraints : Criteria and Constructions
In this work, we provide a geometrical framework for the analysis and design of beamformer codebooks with finite number of beamformer vectors. We present a design criterion for good beamfomer codebooks and show the equivalence ...
Generalized Beamforming for MIMO Systems with Limited Transmitter Information
In this work, we investigate the outage performance of beamforming schemes in wireless systems equipped with multiple transmit and receive antennas. In particular, we analyze the outage performance of unit rank beamforming ...
On Beamforming with Finite Rate Feedback in Multiple Antenna Systems
In this paper, we study a multiple antenna system where the transmitter is equipped with quantized information about instantaneous channel realizations. Assuming that the transmitter uses the quantized information for ...
