Grassmannian beamforming for MIMO amplify-and-forward relaying
Abstract— In this paper, we consider the beamforming codebook design problem for the half-duplex MIMO amplify-andforward relay channel with Rayleigh fading. The analysis is divid...

Optimal beam scheduling for multicasting in wireless networks
We consider the problem of efficient link-layer multicasting in wireless networks with switched beamforming antennas. The inherent tradeoff between multicasting and beamforming ...

Quantized transmit beamforming with antenna selection in a MIMO channel
For a point-to-point multi-input multi-output (MIMO) wireless channel, we propose a feedback scheme, which consists of transmit-antenna selection algorithm and beamforming quantiz...

A multiplicative weight perturbation scheme for distributed beamforming in wireless relay networks with 1-bit feedback
This paper focuses on perturbation-based distributed beamforming with 1-bit feedback for wireless amplify-and-forward relay networks. We propose to use multiplicative perturbation...
