To obtain receiving data of a specified level by suppressing the effect of noise as much as possible and preventing the skirt of a peak in a delay profile from being assigned to a rake finger.

A select path phase detecting section 201 detects the phase of a selected path. A select path range determining section 202 sets a specified range centering a phase detected at the select path phase detecting section 201. A constant determining section 203 sets a constant externally. A threshold determining section 204 sets a threshold by multiplying the peak value by the constant in the select path range determined at the select path range determining section 202. In the range other than the select path range, a threshold having a correlation level lower than that of a threshold set in the select path range is set by multiplying the peak value by the constant.
