Reception section 602 receives a signal on which signals of channels are multiplexed in a same frequency band through antenna 601. Separation section 603 separates a part used for correlation value calculation in the reception signal. Correlation sections 604 and 605 create delay profiles by calculating a correlation value using a 1st basic code and 2nd basic code for the signals after the separation, respectively. Comparison/channel estimation section 606 cycles each delay profile so that the delay profiles match in a section in which the path of the channel to be detected appears when there is no propagation delay and detects a quasi-matching path in each delay profile after the cycling.
