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 ...
Performance limits on beamforming with finite rate feedback for multiple antenna systems
In this work, we address the problem of evaluating the outage performance of beamformers designed for multiple transmit and single receive antenna systems when quantized channel state information is available at the ...
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 ...
