<p>A path search apparatus (30) for detecting path information on a received carrier wave. The apparatus comprises a matched filter (31) for performing a correlation operation of the received signal obtained by converting the carrier wave; a ?f adjustment unit (34) which obtains the frequency deviation of the received signal that is detected through an inverse spreading processing and a combining processing of the received signal that are performed outside the path search apparatus (30), calculates a phase correction value according to the obtained frequency deviation, and corrects the phase that is the result of the correlation operation by the matched filter (31) according to the phase correction value; a delay profile generation unit for generating a delay profile by performing an amplitude addition, a power conversion, and a power addition of the result of the phase correction by a phase correction unit; and a path detection unit (33) for detecting path information on the basis of the delay profile.</p> |
