Abstract
A signal processing method includes receiving a digital signal including a sequence of samples. For each sample among at least some of the samples, a neighbor-based estimate is calculated over (i) one or more samples that precede the sample in the sequence and (ii) one or more samples that succeed the sample in the sequence, and an error value, indicative of a deviation of the neighbor-based estimate from an actual value of the sample, is calculating. An impairment in the digital signal is estimated based on a plurality of error values calculated for a plurality of the samples.
