1. A repeater for a wireless communication network, the repeater operative to provide feedback cancellation, the repeater comprising:

  • an antenna array comprising one or more antenna elements; and

    an equalized feedback cancellation loop operatively coupled to the antenna array, and configured to operate on input signals to derive a metric that is employed to increase signal isolation and signal gain,wherein the metric is indicative of level of a transmitter signal present at a receiver, and is a function of correlation between a transmitted signal and a received signal including a desired receiver signal, andwherein the repeater has a delay that allows the transmitted signal to be de-correlated with the desired receiver signal, the transmitted signal is time aligned, and the transmitted signal is correlated with a feedback leakage signal.
