摘要：The span of a linear transversal equalizer filter moves according to the current

positions of the multi-paths to a receiver. The alignment of the filter span is measured

quantitatively with respect to the current positions of the multi-paths. Adjustments are

made to the filter span to enable the linear transversal filter to capture most of the

available energy of the transmitted signal. The low-pass-filtered magnitudes of tap

weights of the linear filter are multiplied with values of a function which has zeroes at

desired points for the larger tap weights, and a gradient of the function at its zeroes

being non-zero. The magnitude of the alignment measurement signal is used as a

quantitative measure of the alignment of the equalizer span, while the sign of the

alignment measurement signal can be used to decide the direction that the span should

be moved in.
