<p>PROBLEM TO BE SOLVED: To suppress a configuration for calculating correlation values to a min. scale and also to shorten the time required for identifying a long code. SOLUTION: A group-setting part 206 controls a spread code generating part 207, permits the plurality of long codes to be inputted successively to an adder 208 and groups them. The adder 208 adds a plurality of inputted long codes by chip unit by every group, a correlation part 204 calculates the correlation values of the added long codes with a receiving signal and a max. correlation value detecting part 205 selects the group indicating the max. correlation value. Then the long codes belonging to the selected group are divided into a plurality of groups again by the group setting part 206 and are repeated until the long codes in the group comes to be one so that the long code is identified.</p> |
