Abstract
Embodiments of a repeater environment can be operative to deploy a feedback cancellation loop that is adaptively coupled with an antenna array such that a selected metric can be applied to the antenna array and feedback cancellation loop combination to improve signal integrity and amplification. Illustratively, the feedback cancellation loop of the exemplary repeater can be adapted by a metric that operatively adapts weights provided by performing a selected linear algebra technique to the feedback cancellation loop such that the metric can be indicative of the level of transmitter signal present at a receive and can be derived based on performing a correlation between the transmitted signal and the receiver signal. Further, operatively, the exemplary repeater can maintain a delay sufficient to preferably ensure that transmitted signal is de-correlated with the desired receiver signal, and time aligned and correlated with the feedback leakage signal.
