Abstract
A path detection apparatus for use in a CDMA reception device includes: storage means for storing a delay profile; and path detection means for detecting a path by reading the delay profile from the storage means, and performing a rake-combining process based on the read delay profile. With the configuration, the path detection means includes: reference path detection means for detecting a reference path for detection of a probable path based on the delay profile read by the storage means; and detection means for detecting as a probable path in the rake-combining process a path existing in a path detecting time in which reception characteristic of the CDMA reception device can be improved from the detecting time of the reference path detected by the reference path detection means.
