Abstract
A method in a receiver includes receiving a signal that traversed a multipath channel having a channel response, so as to produce a received sequence of samples that are indicative of the channel response. Using a predefined similarity measure, multiple metrics between the received sequence of samples and multiple respective candidate sequences of samples are calculated by the receiver. Each candidate sequence includes a combination of one or more dominant signal components having respective sample delays, and each candidate sequence corresponds to a channel multipath candidate that has one or more channel paths at the respective sample delays. The channel response is estimated by the receiver, by selecting the candidate sequence that best matches the received sequence, the selecting being based on the similarity measure.
