Distributed Transmit Beamforming using Feedback Control
The concept of distributed transmit beamforming is implicit in many key results of network information theory. However, its implementation in a wireless network involves the funda...

Analysis of adaptive feedback and echo cancelation algorithms in a general multiple-microphone and single-loudspeaker system
In this paper, we analyze a general multiple-microphone and singleloudspeaker system, where an adaptive algorithm is used to cancel acoustic feedback/echo and a beamformer process...

Robust Beamforming for Security in MIMO Wiretap Channels with Imperfect CSI
—In this paper, we investigate methods for reducing the likelihood that a message transmitted between two multiantenna nodes is intercepted by an undetected eavesdropper. In part...
