ABSTRACT:
A path searcher used in a receiver includes a power delay profile generating unit configured to generate a power delay profile based on a signal received by the receiver, a sidelobe generating unit configured to identify a sidelobe component of a path contained in the power delay profile based on a response characteristic of a band-limiting filter of the receiver, a sidelobe removing unit configured to remove the sidelobe component from the power delay profile to produce a corrected power delay profile, and a path timing detection unit configured to detect a path timing based on the corrected power delay profile.
