ABSTRACT:
Systems and methods are provided for determining effective tap values for a digital filter. A first plurality of vectors is generated, wherein each of the first plurality of vectors represents a set of tap values for the filter at a first resolution. A best vector is selected from the first plurality of vectors according to a first performance metric. A second plurality of vectors is generated within a threshold distance of the selected best vector, wherein each of the second plurality of vectors represents a set of tap values for the filter at a second resolution that is superior to the first resolution. A best vector is selected from the second plurality of vectors according to a second performance metric.
