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 ...
Design of Multiple Antenna Coding Schemes with Channel Feedback
In this paper, we derive multiple antenna transmission strategies in the presence of limited channel information at the transmitter and the receiver. In particular, we look at the cases of complete channel information, ...
MultiHop Communication is Order Optimal for Homogeneous Sensor Networks
The main goal of this paper is to show that multi-hop single-user communication achieves the per node transport capacity of O(lnN/N) in homogeneous sensor networks, making it order-optimal. Our contributions in this paper ...
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 ...
