Abstract
Enhanced estimation of the noise component of a signal is accomplished by using a plurality of filters. Each filter provides an estimate of a minimum sample in a sample set that includes a plurality of signal samples. A comparator, coupled to the plurality of filters, successively compares the estimates among the plurality of filters, and selects the signal estimate having the lowest magnitude. The selected signal estimate represents an enhanced estimate of the noise component of the signal.
