Patent ID: 7330507

Claim:
In a method for equalizing a multi-channel electronic communication system by employing any initial reference channel of the type wherein input signals and an independently generated noise are received and are converted from analog to digital and the channels are adaptively equalized, and then employing an initial set of equalized data for adaptive beam forming, the improvement comprising the following steps: (a) selecting from the initial set of equalized data a systemically significant number of channels having the largest cancellation ratio; (b) utilizing the selected number of channels as an updated input for a second equalization process applied to then operating channels of the system resulting in a second set of equalized data; (c) employing the second set of equalized data to determine an updated reference channel for input to the equalization process; and (d) repeating the steps (a) through (c) substituting the most recently updated reference channel for the initial reference channel.
