Method for searching for the taps of the influence of reflected signals of an equalizer and devices for the method

Abstract

A device according to the present invention includes: one or more computational units configured to calculate correlation sums of binary-divided first and second parts of the search area specified for a series of discrete digital signals having a unit time difference from one another, wherein the discrete digital signals are specified based on a defined code constant sequence, and a controller configured to specify as the search area a part in which a dominant value appears in one or more correlation sums for the first part and one or more correlation sums for the second part, each calculated by the one or more computational units, and to cause the one or more computational units to recalculate the correlation sums for each of the binary-divided subparts of one part.
