Mobile communication system in multi-carrier CDMA scheme using short code and long code

摘要

In the mobile communication system in the multicarrier 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. <IMAGE>
