Abstract  Abstract

A kind of system and method which can use one short code radiated form user unit to base station to control radiated power during signal passage establishment period of CDMA communication system and initial power enhancing period. That short code is a sequence for base station detecting it has the period far shorter than the period of traditional transmission code. The power enhancing is started at one power level which is guaranteed to be lower than the power level required by the base station to carry out detect. The radiated power of the user unit is increased rapidly while the short code is being radiated by the user unit repeatedly till its signal is detected by the base station the using of short code limits the power excess and its interference to other user table and it also allow the base station and transmission code used by the user unit work in phase.
