More carrier cdma mobile communication arrangement with a short and long code

摘要

In the mobile communication system in the multi-carrier CDMA scheme, data to be transmitted by the radio base station are doubly spread by using a long code that is unique to each radio base station and to be used in identifying each radio base station, in addition to a short code to be used in identifying each mobile station. The long code has a repetition period longer than or equal to the number of sub-carriers used for transmission.
