A group division setting section (206) divides plural long codes into groups by means of inputting plural long codes to an adder (208) in order by controlling a diffusion code generation section (207), the adder (208) adds the inputted plural long codes for every group in a chip unit, a correlation section (204) computes a correlation value between the added long codes and a received signal, a group showing a maximum correlation value is selected by a maximum correlation value detection section (205), a long code belonging to this selected group is divided again into plural groups by the group division setting section (206) and, by repeating this until the long codes in the group become one, the long code is identified. |
