Patent ID: 8619837

Claim:
A repeater for a wireless communication network, the repeater operative to provide feedback cancellation comprising: a metric module configured to perform calculations for weights used by the repeater, and to generate a composite metric derived from metric execution of one or more of an adaptive algorithm, beam forming, and filter bank approach; and an adaptive antenna array cooperating with the metric module to condition signals as part of calculating the composite metric to improve the feedback cancellation; further comprising producing a pilot energy measurement using one or more repeater values comprising a set of time series of one or more post cancellation receive frequency bins, time series of post cancellation receive signal associated with the desired carrier signal frequency channel; further comprising measuring the average interference as a correlation of one or more repeater values comprising a set of time series of one or more post cancellation receive frequency bins, time series of post cancellation receive signal associated with the desired carrier signal frequency channel and a cooperating wireless communication channel value to generate the average interference value, the average interference value described as the non-correlated energy of the wireless communication channel.
